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.
