The code here is: drivers/hv/channel.c 460 BUG_ON(ret != 0); 461 t = wait_for_completion_timeout(&info->waitevent, 5*HZ); 462 BUG_ON(t == 0);
So it calls BUG_ON() if the teardown takes more than 5 seconds. It's most likely that there is a race condition somewhere. It's also possible that it's just taking longer than 5 seconds for some odd reason and the bug would go away if we raised it to 60 seconds. BUG_ON() after 5 seconds seems like a very aggressive thing. regards, dan carpenter _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
