excerpt of /var/log/messages including suspend and resume and start of reboot.
Description of problem:
On attempted resume from suspend, system locks up with text-mode kernel error logging message:
general protection fault: 0000 [#1] SMP
Version-Release number of selected component (if applicable):
2.6.40-4.fc15.x86_64 #1 SMP Fri Jul 29 18:46:53 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
intermittent. Could this be related to having an external USB SATA drive adapter attached?
Attached please find excerpt of /var/log/messages.
Active Peripherals at time of suspend:
* External Monitor
* USB SATA Adapter
* The Adaptor previously known as eth0, now more meaningfully labeled em1
I doubt the USB SATA drive is really impacting this much. Have you been able to hit this more than once? There is also a newer kernel update in F15 now, and while I don't see anything that would immediately seem to fix this issue, it is always worth testing.
