I get the same errors as listed above during resume from suspen (RAM) on Ubuntu
PPA kernel 2.6.35-rc5 (x86_64 Ubuntu 10.04 with ATI X1400 mobile chip in
Thinkpad T60). On my system the screen displays the errors and hangs on the
VT/framebuffer and requires a hard reset.

Additionally they are always proceeded by pciehp messages complaining that a
device already exists (maybe related here?). This is what I see:

[   70.630060] pciehp 0000:00:1c.0:pcie04: Device 0000:02:00.0 already exists
at 0000:02:00, cannot hot add
[   70.630063] pciehp 0000:00:1c.0:pcie04: Cannot add device at 0000:02:00
[   71.336223] usb 3-1: sierra_reset_resume
[   72.160012] [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than
1sec aborting
[   72.160016] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing
EB96 (len 86, WS 4, PS 0) @ 0xEBC9

(there may be a typo or two, the errors above were written down by hand)

I have been having the pciehp errors (and subsequent hang) during resume since
I installed 2.6.34 stable, the atombios errors appeared in the 2.6.35 RCs I
think.
