 Posted: Sun Jul 02, 2006 2:50 am Post subject: udevd problem (solved) |
 |
|
This is the first time i noticed udevd starting up at the boot process and its giving me some problems here. Im so observant 
It first started when i tried to upgrade to the 2.6.17 kernel, when it first came up i got this error
| Code: |
udevd[1226]: init_udev_socket: error getting socket: Address family not supported by protocol
udevd[1226]: main: error initializing udevd socket: illegal seek
|
I then recompiled my 2.6.16-r3 kernel to remove old hardware and now im getting the same error with that kernel.
I have no clue where to start with this, maybe a kernel error some how that i missed? Or maybe some udev links? Iono

Similar problem here. I upgraded my kernel to 2.16 and it was fine. I rebooted a few times without error. Then I made a minor change to my network settings in order to get wifi up (enabled generic IEEE under Networking and enabled Intel Pro 2200BG under Devices->Network Devices). I do not think that my wireless changes in the kernel can have caused this:
Now I get the "unsupported protocol" error. To make things worse, it is preventing me from booting so I cannot simply experiment with my kernel config.
Can anyone tell me/us what is causing this? I can't do anything because even though /hda2 was correctly initialized (reiserfs) and shows success in dmesg I cannot load my root directory because /dev/hda2 cannot be mounted. (failed to open /dev/hda2, no such file or directory).
It appears that hda2 is fine, but it's like there is no entry in /dev for it.

AND... for the first time ever, I deleted my old /boot/bzImage accidentally before backing it up so I don't even have the OLD kernel to boot from!
What's a boy to do?

these might be well off the mark but what the heck
Kysen,
is it possible you have recompiled kernel that was allright 2.6.16 with the config file from troublesome kernel-2.6.17?
an outside chance but admittedly it doesn't make much sense at face value.
The error it gives looks like it comes from a selection in .config not being there but should.
frozenJim,
here's a possibility.
I've seen that appear in the last few days. I had been swapping hard drives. It turned out to be a 'loose' connection of the cable connector into the hard drive.
It didn't appear or feel loose, but with simply re-fitting them, the hard drive re-appeared.

I considered that, which is why I checked dmesg to confirm that /hda2 was being mounted properly. It's there as far as ReiserFS can tell - and that's probably a pretty solid indicator. 
Unless there is some way that I'm misreading the ReiserFS info... But I doubt that my laptop has a loose HD connection on the day that I upgrade my kernel.
Also, the fact that NONE of my /dev devices have been created is an indicator that it's a more systemic problem.

from what are you observing your laptop's hardrive? as in is it the same as you are using to post these queries.
The looseness is probably not the cause as you say, though the loosenes refers to now and not to the time you installed.
The main point is do you have concurrent access to the laptop's harddrive from the system you are using?

No, I have no access to THAT part of the laptop at all. Can't ssh in, can't login.
Fortunately, I dual-boot XP so that's where I am right now. If I can find out what needs to be fixed, then I will LiveCD in and do the fixing. But first I need to have at least a guess as to what might be wrong.

You are working from XP which is in fact on the same hard drive, yes?
Seeing you are in Canada, the locall corner computer shop may have just the thing for you.
I got it from a computer magazine a couple of years ago, a superceded freebie.
extfs anywhere
is the name of the program. It is a windows program which ofcourse equips windows to contact linus partitions.
Just the thing. I can't remember the company, Paragon I think. Southerners like me don't have it available in the country.
Otherwise there is Slax or knoppix or Simply Mepis et al. giving access from the cd.
That concurrent access is what I have come to rely upon. Feel crippled without it.
I'd be thinking of repartitioning, making a third partition big enough to get a clone of damaged gentoo onto,
put into it a complete new gentoo kernel complete with .config and make a replacement kernel for the lost one.,
and /or
get a stage3.tar.gz onto the repairer partition 3,
open it up
it can supply a source of spare /dev*
Also, this sudden mass disappearance brings to mind the possibility of hardware corruption.
I have not had it much myself but a recent post from one of your fellow gurus made mention of it. suggested to do a memtest.
good luch

| What does udevd do, anyway? It's not running on my laptop which is a fresh install, and I don't remember reading about it. But I've got it on my desktop, who knows why. |

I'm thinking that my problem is just a switch I forgot to set in my kernel. I found an old kernel (whew!) and can boot just fine if I use it. It's just my new kernel that causes the problems. So I'm not totally screwed, I booted from the old kernel and emerged some packages and now I am able to make my kernel at least. I'll find it by trial and error eventually.
This is a good sign that there's no hardware problems. It's all my fault - bad kernel config.
I don't know for sure if udev is the problem - but it sure looks like the most likely culprit.

You must be KIDDING!! sigh... who knew? This is the expected price we must pay for "trimming" the kernel of features we know nothing about.
Yep, that was it - you hit the nail right on the head. Thank you SO MUCH!

It can't be modular either... has to be built in...
pwnt!

Thank you so much !!! (been looking 2 days to solve this problem)
I'm new (again) to gentoo and I just thought with my fresh install, well let's compile everything for the network after my gentoo boots. Was I wrong. Didn't know it was needed for udevd...
Now I'm for the first time (again) on the gentoo comand prompt |

I needed to also make sure that Packet socket was selected.
I guess that's what I get for not building a fresh system for a long time. The process keeps changing.
Running like a champ now, though  |
