freeze: kernel BUG at drivers/gpu/drm/i915/i915_gem.c

[Arael]

Hi,

occasionally, when I try to suspend or hibernate my laptop freezes.
Any suggestions?

I tried to google this problem but didn't find a fix. There are several bugs releated to this file but the line is not 4238.
Should I upgrade to kernel 2.6.38?

I have upgraded to 2.6.37.6. I let you know if this solves or not the problem. It seems to me that I'm the only one having these problems.

[djemos]

I have a
VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03)

and from lsmod i see that loads i915 driver

I had upgraded from 13.1.2 to 13.37 and also made a clean install of salix 13.37 and under kde system breaks up and freeze (crash) without reason even if i set composite off.
Kernel is 2.6.37.6.

It is intel driver problem.
I suggest to install a different intel driver 2.14.0 http://ftp.ntua.gr/pub/linux/slackware/ ... i486-1.txz
and see if this solves the problem.

Also try http://ftp.ntua.gr/pub/linux/slackware/ ... i486-1.txz

djemos, did installing mesa and that intel driver solved the problem for you? Because the driver you are suggesting is an Xorg driver while the log is pointing out that the problem is inside a kernel file.

I think that the problem both of us are experimenting is kernel releated.
It seems to me that the only way to fix this is by upgrading the kernel.
If the release .37 doesn't contain a fix for this bug maybe we should try with the .38 versions.

It is incredible, I have stopped using Archlinux because I needed more stable machine and here I am with a crashing Slackware.

Here https://bugzilla.kernel.org/show_bug.cgi?id=26932 a suggestion is to disable the framebuffer by passing this parameter during boot:

Code: Select all

i915.powersave=0

I will first try that and then if this doesn't work I will upgrade to the last stable kernel (2.6.38.6 at the moment.)

Because upgraded my main system where i have all of my work, emails, etc from salix-kde-13.1.2 to salix-13.37, my system became unstable and crash needed a cold reboot, I installed again salix-kde-13.1.2 in another partition and copied /home to the new system so i had again a stable system without loosing my job.

what i said about intel-driver and mesa i read it in internet and did not check it by myself. Maybe we face a different problem related to intel kernel driver. But it is the first time slackware-kde is really unstable and unusable in laptops with intel graphic chipsets.

Edit: I found why kernel crash. I installed salix-xfce-13.37 and kernel crash. Same with KDE. The problem was not kde or xfce or slackware but ndiswrapper. I had setup my wireless card net8187b with ndiswrapper and kernel crash. The windows driver is better and faster. In salix-13.1.2 ndiswrapper wors fine. But new version included in salix-13.37 crash the kernel. So i removed windows driver net8187b and use linux rtl8187 driver.
