Subject: occasional kernel hang on shutdown - kernel/cgroup_pids.c
Date: Tue, 8 Dec 2015 08:53:52 +0900 [thread overview]
Message-ID: <20151207235352.GW15569@logic.at> (raw)
Dear all
(please Cc)
running 4.4-rc4 (written as rc3+ but only the tag commit is missing),
but I think also earlier in the rc releases, I occasionally see hangs
on shutdown. Nothing works anymore, but this time at least there
was some output on the console.
Manually copied from screen:
WARNING: CPU: 1 PID: 14 at kernel/cgroup_pids.c:97 pids_cancel.constrprop.8+0x2a
Modules linked in: ....
...
CPU: 1 PID: 14 Comm: ksoftirqd/1 Tainted: G O 4.4.0-rc3+
Hardware name: Sony Corporation SVP1322A1J/VAIO, BIOS R2092V7 04/24/2015
...
Does that help in any way?
All the best
Norbert
