Bug#843349: linux-image-4.7.0-1-amd64: Intermittently high system load, sluggish response, no /proc/<pid>/stat utime,stime,etc. reported

[Tom Lee <debian@tomlee.co>]

Tried 4.8.0-1 with similar results. Perhaps slightly better, but not much.

$ uname -a

Linux desktop 4.8.0-1-amd64 #1 SMP Debian 4.8.5-1 (2016-10-28) x86_64 GNU/Linux

Like 4.7, can't see what's hogging the CPUs as per-process CPU stats don't appear to be correctly reported in /proc/<pid>/stat.

4.6.x continues to be perfect with respect to both overall performance and the correctness of /proc/<pid>/stat.

Please do.

Nothing is ever a complete failure; it can always serve as a bad
example.
