[first reported at https://bugs.freedesktop.org/show_bug.cgi?id=22886, but
seems like kernel problem]
Hi,
I have a ThinkPad X300 here, with a GM965 inside. Running kernel 2.6.30.1 (and
2.6.31-rc3), xf86-video-intel 2.8.0 (also happened with 2.7.1), xorg 1.6.2. Ah,
and its all x86_64 here, Debian Sid.
When I have KMS enabled, about 50% of my resumes from hibernate (s2disk either
via uswsusp or plain "echo disk > /sys/power/state") end up absolutely fubar: X
is there, I can move the mouse, type, the running apps run fine, but new ones
segfault right after the start (or die with an assertion error). Same happens
when there is no Xorg loaded, with only a 1440x900 console and /sys/power/state
suspend.
As soon I disable KMS, I can't reproduce this behavior anymore.
