Comment 39 for bug 559163

When suspending undocked, my dmesg results match what getriebesand reported, with a similar hardware setup (no external monitors, using internal LCD).

[ 1.009300] PM: Resume from disk failed.
[ 1.009313] registered taskstats version 1
[ 1.009570] Magic number: 0:53:725
[ 1.009574] hash matches /build/buildd/linux-2.6.32/drivers/base/power/main.c:433
[ 1.009601] block loop5: hash matches
[ 1.009670] pci 0000:01:00.0: hash matches

From lspci:
01:00.0: VGA compatible controller: ATI Technologies Inc Radeon RV250 [Mobility FireGL 9000] (rev 02)

Interestingly, in examining the log from successful suspend/resume while docked, I find this:

[ 0.561437] PM: Resume from disk failed.
[ 0.561464] registered taskstats version 1
[ 0.561751] Magic number: 6:891:674

No hash matches follow. I'm not quite sure why PM is reporting a suspend failure when it clearly works in this instance.

If it would be helpful, I can post the dmesg results from both tests. Unfortunately, the log file for suspending while undocked was cut off after a bonobo-activation segfault so I'm not sure how much use it will be. Should also note that I have not experienced the other bug (https://bugs.launchpad.net/bugs/583891) that getriebesand shared.
