And it seems that I don't have linuxrc-file in my machine. Does it come with the genkernel-package? _________________ ---

I think it's generated by genkernel. You can't see it because it gets bundled up in the initrd file that genkernel creates. _________________ Don't let THEM immanentize the Eschaton! |

Epikuros, yes I do recommend that you use genkernel, it's
the gentoo way of building the kernel, it does a lot
of things for you without restricting you from tweaking the
kernel.
try, it
Code: |
genkernel --menuconfig all
|
make sure that you mount your /boot partition, and that
/usr/src/linux point to the directory of the kernel you are
building.
should you encounter any further problems, please post
the link to your kernel .config file, and we will all pitch in
and assist you in resolving any issue which you may encounter.
happy gentooing

the new config can be found at the old place
here's the new section of grub.conf:
Code: |
title=Development Kernel
root (hd0,0)
kernel (hd0,0)/boot/kernel-2.6.3 root=/dev/ram0 init=/linuxrc real_root=/dev/hda4 vga=0x317
initrd (hd0,0)/boot/initrd-2.6.3
|
And here's the messages appearing at boot time:
Code: |
Gentoo initrd startup...
STEP 1: Command-line parsing
STEP 2: Module loading
---- Scanning for ehci-hcd...cat: /modules.cache: No such file or directory
[many modules get loaded, uhci, usb-ohci and eth1394 are not found]
STEP 3: Mount necessary filesystems per boot option
Started device management daemon v1.3.25 for /dev
STEP 4: Determining root device
Root block device unspecified or not detected.
Please specife a device to boot, or "shell" for a shell.

I was having this probelm over the last couple days as well (my OP) .. I am still working out exactly how I fixed it .. but to get the system to boot, I did the following:
Assigned /usr/src/linux to /usr/src/linux-2.6.3
genkernel all --menuconfig
I enabled all the devices and all the options under the follow areas.
Code: |
Device Drivers
ATA/ATAPI/MFM/RLL support
File Systems
Advanced partition selection
|
After genkernel completed, I emerged my nvidia-kernel and hotplug and updated lilo
Code: |
image=/boot/kernel-2.6.3
root=/dev/ram0
label=2.6.3
append="root=/dev/ram0 init=/linuxrc real_root=/dev/hda4"
initrd=/boot/initrd-2.6.3
|
I rebooted no problems, just have a 2.5MB kernel which I am trimming down piece by piece until I find what was causing it to break. So you might try building a monolithic style kernel .. even though you know you don't need some of it, just enable it anyway, you can always disable stuff and compile stuff as a module later.
Don't know if this will work for you, but worth a shot.
Thanks. |

Didn't work. I left the following options out from "ATA/ATAPI/MFM/RLL support" as they don't seem to do anything useful. If you can trace your problem to these options or if they may have some other important use I'm willing to try them too:
Code: |
Use old disk-only driver on primary interface
Boot off-board chipsets first support
Force enable legacy 2.0.X HOSTS to use DMA
Enable DMA only for disks
|

Well, since nobody has told any further suggestions I will try with those options enabled that I disabled above.
And I will naturally tell the results here then. _________________ ---

So...anyone solved this Problem yet? My 2.6.0 is working....but when I recompiled with exactly the same config suddenly the Error occured (also at 2.6.3 vanilla/dev/mm1). |

Same problem here, with gentoo-dev-sources-2.6.3-r1 (no genkernel):
VFS Cannot open root device hda1
Checked and double checked all the tips from the 1st post
My config
Should we submit a bug? |

Yeah, I am too beginning to think we should report this as a bug. It may be hard to get the programmers believe this is a bug though because of the people that have the problem just because no support to ext3-fs/reiserfs is enabled and of the cases that have been resolved magically just by tuning some advanced partition-section. _________________ ---

with that in mind, maybe we should post some hardware details - there must be some common factor here. If we could say "it seems to be a problem with XXXX chips..." it would lend some credibility to the matter.
I'd start, only I'm not at home right now, so it'll have to wait until monday. _________________ Don't let THEM immanentize the Eschaton! |

Ok, I think I've found the solution.
I was using the option
File systems ---> Partition Types --->[*] Advanced partition selection --> [*] Windows Logical Disk Manager (Dynamic Disk) support
but the correct one is
File systems ---> Partition Types --->[*] Advanced partition selection --> [*] PC BIOS (MSDOS partition tables) support
Hope that it helps. |

Hmm... I had both of them enabled. Are you suggesting that I should disable the Windows Logical-thingy? _________________ ---

If you have the PC BIOS support , I don't think disabling "Windows Logical Disk Manager" will help, but you should try, you don't risk anything.
Are you sure you have rebooted with the new kernel settings? I've read some people has too solved the problem activating the PC BIOS support

I'm still suspecting a bug. I should still test more unreasonable configurations before I start submitting any bugs though. I'm just lazy to test as the 2.4-series is working fine. Maybe I have to start testing at least when the gentoo-sources-package moves to 2.6 if not sooner. _________________ ---

Hi guys, ive seen the same problems... Ive prolly been building my kernels for 4 years now and never had a problem, i usually build everything as inbuilt as long as its part of the boot process.. I strip out stuff i dont need.. I love gentoo and ive got like 4 servers at work on different hardware and so on..
But a week ago i tried to install gentoo on a IBM portable and a vanilla HP vectra.. Both fail on the same spot in the boot process.. unable to boot on root and tons of LBA errors infront of it... Ive done exactly what ive allways been doing when configuring the kernels and i have no clue why its crashing now... Only thing new is that im using 2.6.3+ and 2.4.22-r7... tho i have several servers booting and running fine on it...
The common thing on the setup is that im using intel chipsets, gigabit ethernet, reiserfs and its a p4 compiled with gcc 3.3.2
I havent tried the notail option on reiserfs @ root tho.. never been needed before tho... After several days of headbanging i thought that this could be hardware error because of the spew of LBA errors before it complains on the mounting problems.. but i installed suse 9.0 and it works fine!!! no errors at all.. So its gotta be a gentoo thing/new kernel thing..
The strange thing is that i get the same problems in 2.4 and 2.6, lilo and grub (well grub segfaults when i run the grub exe on the Vectra tho..)
i hope we all find out whats bugging gentoo these days!! |

I had same problem today when I reconfigured my 2.6.4-ck1 kernel. Ext3 root fs didn't get mounted. I finally tried to enable PC BIOS support under Partitions Typed and it fixed the problem.
Curiously I didn't have it enabled in the previous kernel I used (2.6.4-ck1 with a bit different configuration) and it worked fine... _________________ Your browser doesn't support signatures. Please use a supported browser. |

|

I would like to add a suggestion to the following instruction:
Quote: | Fix your kernel boot parameters.
Make sure your kernel has a "root=" parameter passed to it in your bootloader and that the parameter points to your root file system. For example, my root file system is on /dev/hde2. My grub.conf contains:
Code: | kernel (hd0,0)/boot/bzImage-2.6.1-rc2-gentoo-1 root=/dev/hde2 |
|
In my case (2.4.25 vanilla-sources kernel, ReiserFS root partition), I actually received VFS panic errors trying to mount my root partition on boot until I removed the "root=" parameter from my GRUB configuration. It wouldn't surprise me at all if a number of the people in this forum also suffered from this problem, because they're following the documentation to the letter... So I suggest adding a note along the lines of:
Quote: | Note:
If you receive a VFS kernel panic error when the kernel tries to mount your root partition, try removing the "root=" parameter from your configuration. |

I had the same problems with the kernel unable to find my root, and I have been working on it the whole day until I saw something that catched my eye on the screen; my compiled kernel did mount my scsi discs in another order than the livecd!!!
This is really funny since grub finds the discs in the same order as the livecd and bios for that matter, but what is /dev/sdb3 in livecd is /dev/sda3 when booting with the compiled kernel.
So now everything works and perhaps someone else can benefit from my strangle mistake |

I noticed that I was having the same problem as F.Ultra, but mine was on the IDE drives (I don't have SCSI). I didn't know how to figure out what the new order was though, so I didn't spend much more time trying to figure it out. Is there a way to keep them from getting re-ordered, or to figure out what the new order is? |

Here's some info about my hardware. My hard-drive is IBM DeskStar IC35L060AVER07-0 and my motherboard ASUS P3B-F
This is what it says about ide-bus in the manual of the motherboard:
Quote: |
2.1.1 Specifications
UltraDMA/33 Bus Master IDE: Comes with an onboard PCI Bus Master IDE controller with two connectors that support four IDE devices in two channels. Supports UltraDMA/33, PIO Modes 3 and 4, and Bus Master IDE DMA Mode 2, as well as Enhanced IDE devices, such as Tape Backup, CD-ROM, CD-R/W, and LS-120 drives. |
Quote: |
2.1.3 Performance Features
Double the IDE Tranfer Speed: ASUS smart series motherboards with Intel chipsets improves IDE transfer rate using Bus Master UltraDMA/33 IDE which can handle data tranfers up to 33MB/s
|
The drive is (is far as I can remember) primary master. Of course the probability of hardware complications still seem rather small as the 2.4 kernel(how many times have I repeated it ) boots just fine.
Oh, I tried with gentoo-dev-sources too, but no success there either... _________________ ---
