Not this particular one, but you may try to move pm_finish() after resume_console() in kernel/power/main.c:suspend_prepare() and see if that helps. If it doesn't help, then try to compile the kernel with NO_HZ and HIGH_RES_TIMERS unset. If that doesn't help, you may try with HPET_TIMER unset additionally.
Okay, my system is doing it with a known good kernel as well (2.6.21-rc4), so this is something else. Please ignore my report for now. In the meantime, I'll be downgrading my hal and drm to what they were a week ago to see if that fixes the problem. (I knew better than to change more than one thing at a time, really I did. Sigh.)
