eth0 completely gone

[viking60]

After my last Arch update my eth0 is completely gone. Not network no internet no nothing. Can anyone help?

If I know what all updated, I may be able to, although mine is working.

Well I fixed it -sort of. I rebooted and picked fallback on the boot menu. Then it booted into an environment where eth0 worked. Played arround a little bit and rebooted and went back into the normal environment and eth0 was back.
This must be a Kernel thing.

What's the output of uname -a ?

Also, if there's an error for eth0 on boot, what is it? Don't know if this is the issue or not, but I found this thread for Arch - it's outdated, but could it be the issue?

Also, I'm not finding anything current on it at their Kernel & Hardware issues section... you might check, though?

Thanks.

uname -a

There is no error on boot. It is a Kernel thing most likely Modbrobe b44.

And it is no wonder you can't find anything in the Arch forum, they are all without an internet connection now

LMAO. I'm on the same kernel. This is strange...

Code: Select all

 uname -a
Linux dedanna.rocks.net 2.6.35-ARCH #1 SMP PREEMPT Wed Sep 29 07:17:20 UTC 2010 i686 Intel(R) Pentium(R) 4 CPU 2.40GHz GenuineIntel GNU/Linux

Arch Linux eth0 is gone search

I agree this is a kernel issue

some errors might not be found by debugging
writing slc programs can be the same way (you can debug the steps and they work fine)
but fails on the operation (usually a timing issue)
we run debug in this order step, section, and whole

And it is no wonder you can't find anything in the Arch forum, they are all without an internet connection now

i wonder how they feel right now
we do what we can to solve issues
it never bodes well to be in a hurry and go too fast because you may miss the problem that is usually staring you in the face

viking, is there anything in dmesg?

I quite like the Arch forum myself - has been helpful a time or two.

[viking60]

Are you still trying to help me? The problem is solved.
But it beats me how the eth0 disappeared in the first place. Since it worked in the fallback it indicates that it was a Kernel issue. This is a known issue when updating the Kernel and has also been commented in the Arch forum.
There is a lot in dmesg. But what should I look for when there is no error?
