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

Patches just got merged into mainline. Please let me know if the
current git master doesn't fix the issue.
Thanks.

Hi Tejun,

Seems to have worked - I don't see the kernel hangs anymore. What remains
are problems with DRI/DRM, but I will report separately.
Thanks a lot
