I've traced this down to the get_cmos_time() call - a printk before that appears, one afterwards doesn't. The rest of the time, resume works correctly. Interestingly, this only seems to happen if I use the patch from http://bugzilla.kernel.org/show_bug.cgi?id=2643 or a similar one for the IO-APIC. Does anyone have any idea why this might result in this sort of failure mode? I'm considering just removing the call for now and resetting the clock from userspace. -- Matthew Garrett | mjg59@srcf.ucam.org
