Hi,
with kernel 2.6.35-rc5 I'm seeing a problem which happens every few
hibernate/resume cycles.
When I resume my computer, X is black (only the mouse cursor is
visible) and the X server outputs a stack trace to the VT. Changing to
the VT and back restores xorg correctly. dmesg says:
[118132.523397] video LNXVIDEO:00: Restoring backlight state

This would not happen with 2.6.34. My hardware is a GM45.
any idea what this might be?
Regards,
Pedro

Looks like we got the ordering wrong. My guess is that we enabled the
backlight controller whilst the pipe was turned off. Can you try and
capture the error/dmesg with drm.debug=0xf? Meanwhile, it's time to hit
the docs and see if they have any advice.

I just hit the bug!
Unfortunately there is so much output that dmesg does not show
anything useful - the log is so big that it gets cropped before I get
a chance to see it.
I've stopped rsyslog since it kept filing up my root partition to
100%... Should I reduce the debug output?
Regards,
Pedro

dmesg | more

That's not what I meant. It appears my dmesg buffer has a limit of
around ~1200 lines, which fill up in 0.2s. Since the debug output is
so much, when I hit the bug and go see dmesg, it is already gone.

Sorry about that, it just was the first idea that came into my mind. My
apologies.
