Xorg log and output of pciconf -lbev
These problems started probably after I upgraded all my packages, which then upgraded the X11 intel DDX driver. I am quite sure suspend to RAM worked fine before that.
If I do suspend to RAM when switched to console first, there is no problem.
Previously, probably before the intel DDX upgrade, the system would switch to console tty, then suspend, and during resume would switch back to X11 context.
I managed to get a crash dump. Here is a backtrace:

I've attached some files which describe my setup:
- Xorg.0.log.old - file /var/log/Xorg.0.log.old
- pciconf.txt - output of pciconf -lbev
The attached files are captured or created just after the reboot from crash.
Because the attachment size limit is 1M, I have uploaded the crash dump here:
Can somebody check if there's anything that could be done to make this work? Unless this is fixed, I will have to shadow the zzz -utility with a shell script that forces a vty switch to console before invoking the original zzz. But that is an ugly kludge in my opinion.
At the time of crash I had not started web browsers or any other software which would keep password or other similar things in memory, so I hope that crash dump don't contain any info that can be used by randoms and/or botnets to hack me.
