Hi, In continuing to replace, where appropriate, code with msleep() calls, I ran across the following file(s) / function(s), which do not invoke set_current_state() before schedule_timeout(), which causes the latter to return immediately: drivers/net/tokenring/ibmtr.c::ibmtr_cleanup_card() If someone could tell me which state (TASK_INTERRUPTIBLE or TASK_UNINTERRUPTIBLE) is desired, I can fix this and perhaps replace the calls with msleep(). Thanks, Nish
