Description Matěj Cepl 2008-04-19 20:20:41 UTC
Description of problem:
When trying i915.modeset=1 on my kernel command line everything looks pretty
well, but unfortunately, from time to time Xorg crashes and then it gets into
endless cycle of restarts (either fast repeated Ctrl-Alt-Del or power off is the
only solution).

Version-Release number of selected component (if applicable):
mesa-libGL-7.1-0.25.fc9.i386
xorg-x11-drv-i810-2.2.1-20.fc9.i386
kernel-2.6.25-1.fc9.i686
[matej@viklef ~]$ uname -a
Linux viklef 2.6.25-1.fc9.i686 #1 SMP Thu Apr 17 01:47:10 EDT 2008 i686 i686
i386 GNU/Linux
[matej@viklef ~]$ 

How reproducible:
5 out of 5 restarts

Steps to Reproduce:
1.just run Xorg (from gdm) with i915.modeset=1 on the kernel command line
2.
3.
  
Actual results:
crashes from time to time

Expected results:
everything stable as a rock

Comment 16 Igor Bukanov 2008-07-28 10:43:11 UTC
On my Dell Latitude X1 laptop with Intel 915 chipset under Fedora-9 with all
updated as of 2008-07-28 acticating i915.modeset=1 leads to X server crash on
startup. Typically after that I can switch to the virtual console, but only
once. That is, after switching back to X-server F7 screen I cannot switch to any
virtual consoles.

The stack trace from Xorg log file (see the following attachments) always report
a segfault like:
