Yes, it is. This means that suspending/resuming devices works correctly. Please try # echo platform > /sys/power/pm_test and see if that triggers the crash. If it doesn't, please try # echo processors > /sys/power/pm_test and if that doesn't trigger the crash, # echo core > /sys/power/pm_test (this is described in Documentation/power/basic-pm-debugging.txt in the kernel source tree, BTW).
