journald log

After updating from 3.6.6 to 3.6.9 my laptop with Intel graphics and ATI HD
5650 will not resume from suspend. I use vgaswitcheroo to disable the ATI card
at boot. On resume the computer almost hangs (I can press power button and wait
5 minutes for a proper shutdown, but no other interaction is possible). It logs
a lot of messages saying:

[drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting
[drm:atom_execute_table_locked] *ERROR* atombios stuck executing D098 (len 72,
WS 0, PS 0) @ 0xD0C7

Steps to reproduce:
echo "OFF" > /sys/kernel/debug/vgaswitcheroo/switch
[suspend and resume]

Actual results:
Almost freeze.

Expected results:
Resume and work as normal.

Log is attached, but if you need anything else just ask.
