X segvs on resume from suspend to RAM on a Thinkpad R32
Last modified: 2007-11-30 17:11:40 EST
Description of problem:
When coming back from sleep, Xorg on my Thinkpad R32 crashes about 1 out of 5
I see this same behavior with kernel-2.6.17-1.2157_FC5 and
kernel-2.6.17-1.2174_FC5. If I use kernel-2.6.15-1.1833_FC4, I do not see this
problem (the sound works better on 2.6.17).
After the crash, X starts up fine, though it looks like the old vt is hosed, so
it uses the next one.
I currently chvt 1, before resume and chvt 8 afterwards to prevent video from
freezing up, which I observed in 2157_FC5, but not in 1833_FC4.
I also use the radeonfb kernel module at boot to prevent power drain during
suspend, as described here:

Thanks in advance.
Sorry, I forgot that I had filed this.
Some fiddling with my resume script made this go away, and I use a different
You can probably just set this to worksforme.
