Package: src:linux
Version: 4.4.2-3
Severity: normal

I'm having some strange problems with the 4.4.2-3 kernel in
high-load/high-memory-pressure situations with a ThinkPad Carbon X1 (3rd gen)
laptop, with a fault in unlink_anon_vmas.

It tends to hang right after turning on my monitor (which I'm also using with
as an USB hub), or when waking up the monitor from DPMS which causes the hub to
start working again. But I have no clue if it is related really, as I couldn't
reproduce the issue at all under low load situations.

In the log (which is short enough), it starts at the 8242.569150 mark.

I was able to trigger this issue three times in a couple of hours, while
reading intensively from the disk.

Please let me know if there's anything I can do to help.
