PostPosted: Thu May 29, 2014 12:32 am    Post subject: kernel 3.12.20 hangs waiting for uevents, 3.12.13 does not Reply with quote

I have a kernel 3.12.20 (gentoo-sources) that hangs waiting for uevents to be processed, generated from genkernel. The same system boots fine with a 3.12.13 kernel. The .config files are basically identical, I created the 3.12.20 .config from a make oldconfig of the 3.12.13 kernel.

The .config file is here: .config

The system is from a recent stage3 install, and I rebuilt with emerge -e @system && emerge -e @world.

The motherboard is a Asus AM1 with no PCI boards in it:

Does anyone know why the 3.12.20 kernel would hang waiting for uevents?

Thanks Much,
russk

P.S. 2nd try for this post, sorry for any confusion.

Since this broke in a stable series, it should be easy to bisect. First check if the corresponding vanilla sources versions behave the same and, if they do, then please bisect within that range to find the commit which caused the problem.

any news for this? i have exactly the same issue.

The display hangs at "waiting for uevents to be processed" but the system boots without any further issues.
As this affects my server i switched back to 3.8.13 regardless of CVE-2014-0196, but that's no real solution.

So far I have tried vanilla sources 3.12.20 and gentoo-sources 3.14.4 with the same results. I don't see another lower version in portage so I guess I'm going to roll my own. Also when I tried 3.14.4, I went through menuconfig and disabled a bunch of drivers that I did not need but it still hung waiting for uevents. I'll post any updates

Strangely enough, I tried a vanilla kernel from kernel.org, 3.12.15, and it booted fine. I used the .config from the 3.12.13 as the basis for oldconfig.

Then for grins and giggles, I tried to boot the 3.12.20 kernel again and it worked. I believe the difference being that I had reduced the number of drivers but also had fiddled with grub and had gone back and forth from trying to use systemd. So far the system boots fine without systemd, it has different troubles when I try to use the systemd init.

Also by the way, another difference that may be crucial,
Code:
CONFIG_UEVENT_HELPER_PATH="/sbin/udevadm"


This is how it is currently set. I believe it was removed at one point upon recommendation of some emerge advice somewhere.

I have bisected the vanilla kernel and found that the patch

Code:

commit 14adc89298f894816ea2f3aef4d8d2d6ede18575
Author: Christian König <christian.koenig@amd.com>
Date:   Mon Jan 21 13:58:46 2013 +0100

    drm/radeon: Deprecate UMS support v2
   
    KMS support is out and stable for a couple of years now and
    the userspace code has deprecated or abandoned the old UMS interface.
   
    So make the KMS interface the default and deprecate the UMS interface
    in the kernel as well.
   
    v2: rebased on alex/drm-next-3.9-wip
   
    Signed-off-by: Christian König <christian.koenig@amd.com>
    Signed-off-by: Alex Deucher <alexander.deucher@amd.com>


causes this issue.

I'm currently in trying to revert this patch from 3.12.20 and then trying this kernel until i open a bug report at bugzilla.kernel.org.

I will update this post as i have opened the bug.

Kind regards,

morlix

I solved it for me with the new kernel 3.12.21-r1 and installing linux-firmware.

Please report if this solves this for you too.

If you want, i can upload my kernel configuration for you to review and compare with yours.

Only thing I found for it was to force a downgrade to udev-208-r1 by masking anything later and rebuilding.
