[Bug 1006386] BUG: unable to handle kernel NULL pointer dereference during shutdown in __ww_mutex_lock

http://bugzilla.novell.com/show_bug.cgi?id=1006386 http://bugzilla.novell.com/show_bug.cgi?id=1006386#c2 --- Comment #2 from Ladislav Mate --- Seems to be regression from previous kernel,tested this with kernel 4.6.3-1-default, and system shutdown/reboot is completed without hang. I have found two BUG messages (both __ww_mutex_lock) in shutdown logs from whole history of journalctl , however shutdown is never completed with kernel 4.7.6-1-default and this is reliably reproducible. I'll try to report to upstream. -- You are receiving this mail because: You are on the CC list for the bug.
