I'm not able to do it this way too, so resume seems to be necessary to trigger it. I'm going try with the suspend debug in the "core" mode. > (damn, wish i could s2ram this box) That need not suffice. I have two other boxes that suspend and resume correctly with 2.6.32-rc, AFAICS. However, there seems to be a systematic error somewhere, since the failure always happens at the same place, ie. list_del_init(cwq->worklist.next); in run_workqueue(), in preemptible as well as in non-preemptible kernels. Which is kind of strange, given the !list_empty(&cwq->worklist) test right before it.
