Red Hat Bugzilla – Bug 32425
Dell Portables and drm error RC2 qa
Last modified: 2007-04-18 12:32:17 EDT
This bug affects Dell potables C600 and I8000.
When at a command prompt switching from init 3 to init 5 will cause the
[drm:drm_release] *ERROR* Process XXX dead, freeing lock of context 1
The (xxx) process number will be different everytime you switch from init
3 to 5.
This is a problem with the DRM module in the kernel.
From what I gather on the DRI lists, this is mostly just a debugging message and
is currently the number one cause of bug reports in their bug database. Gareth
was asking if anyone had any problems with just commenting out that printk and
there weren't any complaints, so just commenting it out may be the best solution.
Fixed this for the next build.

messages file from the drm error
I don't think it is just a debugging error. on my Lat C600, I suddenly get a
blinking screen as if it is trying to get into X but it keeps spewing out the
here is the /var/log/messages
also, I can't go to X anymore, even if I reboot. I keep getting the drm error
messages and blinking screen.
let me know what else you need
Quoting from Rik Faith's message to the dri-devel list
(http://www.geocrawler.com/lists/3/SourceForge/680/350/5293026/) on the thread

Sure. We should probably change the DRM_ERROR to a DRM_DEBUG so that
we'll still see it when we use <driver_name>=debug on the module line.
Is there anything more indicative of what's causing the problem in
/var/gdm/:0.log or /var/log/XFree86.0.log? Especially if it keeps going after a
reboot, I don't think that it's the DRI. A quick check would be commenting out
the Load "dri" line from the modules section of /etc/X11/XF86Config-4
Ok, I figure out what the problem with all the drm error I got is. I had a USB
mouse hooked up to the system. I removed it and restart the machine. I walked
away. kudzu start saying the USB mouse was removed (I did not see this) and
timed out ignoring the mouse removal. it would then try to go into X and will
not work. I think instead of having all the blinking and the drm error, the
screen should spew out a message saying " mouse not found ".
The kernel message shouldn't be an issue in newer kernels according to what
Arjan said; now it's a separate issue of X failing if it can't find its mouse
which is the way things have been for a while. The issue of gdm respawning ad
nauseum is a different issue and not kernel related. Take a look at bug 13623
for more on the gdm issue.
