 Posted: Thu Mar 10, 2016 6:47 pm Post subject: recognisiing new cpu [SOLVED] |
 |
|
Dear Folks,
I have moved the hard dive in my machine to a new box.
It has a different motherboard and cpu.
The motherboard is an asus sabertooth fx 990 and the cpu is an amd FX 8350.
There is an nvidia engt 430 graphics card installed as well.
I am getting read onlly errors when I issue commands.
I have been advised that I will need to recompile the kernel.
I can't do that if I can't open files etc - I think it is a file permission problem.
Suggestions appreciated.
Regards
MF

Can you log in? What sort of errors? Are they boot errors? You say you issue commands, so that means you were able to log in? |

Dear Tony,
I can login as a user and root but the username and domain name is unknown.
A new log file is not being made in /var/liog

When I login as a use and then su to root the prompt looks like this:

the sys and proc directories have been updated to today's date.
A whole load of empty files have been created in sys except one: kcore which is a huge file (some kind of core dump?)

When you change hardware you need to ensure that the instruction set of your old cpu is supported by your new cpu.
It seems you switched from an intel cpu to amd cpu, and the amd cpu does not understand a few of the intel cpu instructions.
What was your old make.conf and cpu?
what is your current cpu and make.conf?

You will get a similar list for your old cpu. This list has to be supported by your new cpu.
Usually it is safe to upgrade intel -> intel (newer)
amd -> amd (newer)
Regardless of the age (only when you did have set generic flags and optimizations, which i highly doubt)
intel -> amd (not good)
amd -> intel (not good)
When you run march = native or special set, ... same, also not the best settings when you switch intel - amd or vice versa
---
Lets assume you have upgraded the hardware, and the hardware is downcompatible (which i doubt as of now)

BAsically, boot up a livecd, chroot and build the kernel. That should be doable when the hardware is downcompatible (which you need to verify, textwall above what i have written)
or
use the kernel from the sysrescue-cd or any bootble kernel to bootup your box. (bootable implies it has all stuff build in for your hardware)
....
I moved this installation here several times from harddrives to better notebooks. I always stayed on the intel side cpu wise, and always upgraded. so my newer cpu understood all instructions / optimizations of my older cpu. I also stayed on the nvidia-gpu side, so also no hassle on that side(but that is not a requirements, as gpus arenot that essential to boot up).
...
please note. a reinstall is sometimes the faster way because you need to adapt your make.conf anyway for your new hardware and you need to build the toolchian and software anyway for your new hardware. it is a clean new install
you can reuse parts of the make.conf and other config files from your previous installation, which speeds up the process.
I personally recommmend to exchange drives every 2 years or less because of used up write cycles, so you have to move the data anyway. Warranty period in my area is 2 years for generic goods.
when you are unable to fix your installation in a reasonable time you may reuse the configs and do a clean install with the gentoo handbook. |

| Posted: Sun Mar 20, 2016 8:42 pm Post subject: on reinstallation genkernel all results in system shutdown |
|
|
Dear Folks,
I decided to reinstall gentoo.
It went OK until I got to the genkernel part.
I did not know what to do with the rc.conf file so I left it unchanged - ie the default one provided in the stage3 tarball.
That is supposed to control system start up and shutdown so maybe that has something to do with it.
Or maybe not.
When I first tried to run genkernel it failed because the directory containing the kernel source has not been created.
I had forgotten to do emerge gentoo-sources.
I did it.
But when I ran genkernel all it started up and ran mrproper and oldconfig etc
and then it said
compiling 4.1.15-gentoo-r1 bzimage.....
and all of a sudden the machine powered down.
At first I thought there was a power failure in my apartment.
Not true.
I then thought e.g. the PC psu had failed etc....
No.
I was running the gentoo installation in a terminal on a debian installation I made and had chrooted into the gentoo root file system to do this.
I rebooted the debian installation and ran it smoothly for couple of hours doing a variety of things before I decided to mount the gentoo partition and do the chroot again.
I did so and tried running genkernel all again and it did exactly the same shutdown trick again.
Is it possible that the kernel being created is somehow sending a system shutdown message?
Would the genkernel log file be in /var/log?
What log files and config files would be useful to post on the site to help with this problem?
Regards

Try /var/log/genkernel.log and /var/log/messages
My guess is that the power supply is insufficient for sustained high CPU use, but I may be way off base. See if those logs shed any light. |

Dear Tony,
Many thanks for your response.
The psu is a 350 MW device taken from a much lower spec pc.
But the asus 990 fx board and FX 8350 cpu only need about 150 W or so and the nvidia engt 430 graphics card 40W or so I think.
I will run a power use calc check.
I will get the log files and post them.
Regards

8350 is a 220W TDP CPU. My Phenom II is 125W TDP. I idle at 120 W total taken from the UPS. When running hard, compiling kernel or a big package like Firefox, it jumps to 220 W from the UPS. PS is a 80% Bronze Seasonic 350W. I'd expect your machine to run 100W higher than mine, which is pushing a 350W PS. PS ratings are a bit slippery as they total all outputs, but some have a lot of 5V capability while 12V is what counts and how much per rail. You may need a 450W supply.
Try setting genkernel to only use one core and see if it survives. I forget where the setting is. |

Dear Tony,
I am struggling with pastebinit.
In gentoo it compiles but when I run it I get this api key error problem
Running it in debian is odd. It creates a link http://www,paste.debian.net or something similar but NOT the extra number to the posted content.
If you go on the site and try to manually post it it complains the minmum post size is 150 kb and rejects it (even small posts too)
I have put the last 100 lines of the genkernel output in here by hand:

Dear Tony,
I cannot see any dmesg file in /var/log.
Maybe that would only be created if I had finished the installation and was booting gnetoo from the hard disk and not chrooting into it from debian before the installation grub and tidy up stuff has been done.

Dear Tony,
I think I understand what you are saying about the power supply.
What you mean is that the compilations of e.g. pastebinit and emacs might have boosted the power requirement somewhat when I did them,
but
compiling the kernel using all 8 processors and optimising it to take advantage of them and any dynamic memory requirements alongside could well use up a lot of power
for short while - but that couldc well be enough to cause a problem and thus the shutdown......................
As the Americans would say "that'll do it"...
You can't fault the gentoo designers for wanting to do the best optimisation job they can with the cpu I have.
They are assuming I would have a power supply that is adequate for the transient requirement needed to produce the best executable obtainable in my case.
I really need to get the old power supply fixed.
It is muscular enough for this box and e.g. a larger graphics card if I would install it.

Try wgetpaste as an alternative to pastebinit. The name sounds like "get" but you are really doing a "put".
Also, try adding --makeopts=-j1 to your genkernel command line. This should force genkernel to use only one core. If that works, definitely we are looking at the PS
If it still crashes with one core only, we are probably looking at something else. |

| If you have to buy a new PSU, don't be stingy. A good 450 W unit (choose at least a 80+ bronze one) is much more efficient than a 750 W noname one. And the voltages will be more stable, so your hardware will last much more time. |

Dear All,
The kernel compiled successfully with makeopts set to -j1.
So there is a problem with the power supply......
My other power supply is a Zalman zm 1250 platinum.
It needs to be repaired.
I will get it fixed and swap it for the current one.
I also emrged wgetpaste.
I will see if I can make it work better than pastebinit.
I will finish off the installation and reboot and then power diown the machine and sort the power supply problem.
Then I will go back to it and do the manual kernel compilation and optimisation.
Thanks

The psu is a 350 MW device taken from a much lower spec pc.
But the asus 990 fx board and FX 8350 cpu only need about 150 W or so and the nvidia engt 430 graphics card 40W or so I think.

350 MW !? Megawatts?
Anyhow, total 350 W does not mean it can provide 220 W or even 150 W on 3.3 V rail. |

OK, I will get the zalman psu fixed.
It can deliver 45A on one 12V rail and 65A on the other as I recall.

By coincidence I inventoried my power supplies today:
my Antec Earthwatts 380 : +3.3V@20A,+5V@20A,+12V1@17A,+12V2@17A,-12V@0.8A,+5VSB@2.5A
my Seasonic S12II 430B: +3.3V@20A, +5V@20A, +12V1@17A, +12V2@17A, -12V@0.8A, +5VSB@2.5A EXACTLY THE SAME BUT RATED 50 WATTS HIGHER
my Antec Earthwatts EA500: +3.3V@25A, +5V@24A, +12V1@22A, +12V2@22A, -12V@0.8A, +5VSB@2.5A
Seasonic is a manufacturer and Antec is a reseller, in fact I believe the Earthwatts series is made by Seasonic, except for the models ending "D" which are made by Delta.
Edit:
The CPU is usually run off it's own 12V rail. The FX-8350 does appear to be 25W, not 220W as I thought. That would be 10A at 12V at 100% efficiency. You don't want to run these supplies on the ragged edge, but a 17A supply should be sufficient. Maybe the supply is a single rail and feeding the video card too?
The Seasonic above has trouble with my Phenom II X6 1090T, also 125W, three hard drives, ethernet card, HVR-1600 TV card EVGA GS8400S video card. What are the specs on your supply?
Also, did you try running genkernel with only one core? What were the results?
The CPU also may have just got too hot and shut down. Have you blown dust out of the heat sink lately? |
