Description Ivan Baidakov 2009-06-07 03:35:02 UTC

When I do hibernate-ram and than resume, my kernel hangs. Sorry, my there are no messages left in /var/log/messages. I tried in-kernel drm and linux-drm-20090320-kernelsource.tar.bz2.

My video card is : ati radeon xpress 200M.
X.Org X Server 1.5.3

Can you take a picture of the kernel panic or console output?

Comment 2 Alex Deucher 2009-06-08 07:19:51 UTC

This may be a dup of bug 22140.  Can you confirm?

Comment 3 Ivan Baidakov 2009-06-08 10:10:43 UTC

It probably much more bug 19581, but I'm not sure. Mores exact problem description:
My PC does resume after hibernate-ram, even X desktop is displayed correctly, but all newly launched programs do "coredumps" and some time after even launched-before-hibernate programs do coredumps. I'm not sure, but kernel log (alt+f12) displays always new stack traces. 

Here are some logs (with with unloaded drm/radeon modules it happens not). For vanilla kernel:

How can I grab console output? Could you point me some docs, how can I do than (I'm not kernel hacker)? If it is ok for, you I can do a photo of my screen... 

BTW, when linux hangs with backtraces it says something about "vblank"...?

Comment 4 Ivan Baidakov 2009-06-08 10:12:36 UTC

Btw, some people report that error disappeared on latest drm sources....
