When I abort the suspend cycle by pressing "backspace" while the image is
written to disk, the X server crashes. If the suspend cycle is not aborted,
suspend to disk works fine without crashing X.

Hi,

I can confirm this bug. On console, with X11 running, no problem.

Thanks for your report.

Hi,

I tested the s2disk in other machine (Lenovo X61, with intel video
card) and the problem is not reproducible.

The problem, in the machine with problems (NVidia Card) is in the
function restore_console (in suspend.c) here:

http://git.kernel.org/cgit/linux/kernel/git/rafael/suspend-utils.git/tree/suspend.c#n1900

Exactly in the call "error = ioctl(fd, VT_ACTIVATE, orig_vc);"

The screen goes to blank, with the backlight enabled, and the system
stops. IMO, the problem seems to be in the video card module/driver.

Cheers,
kix

Indeed, it seems to be caused by 'opensource' Radeon drivers.

Thanks

Hi,

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=594569

Seems the same problem. But I have the problem with noveau driver.
Probably I will clone the bug and reassign it to both drivers. I will
test today if the problem is reproducible with propietary drivers or
with the experimental version of noveau.

Cheers,
kix

Hi,

I tried the testing/unstable version of xserver-xorg-video-nouveau and the problem continues.

I will reassign this bug to xserver-xorg-video-nouveau, but it could apply to xserver-xorg-video-radeon (we need that Heiner confirm it).

Cheers,
kix
