Package: src:linux
Version: 4.5.2-1
Severity: important

Dear Maintainer,

Since today, every time I suspend my laptop and re-awake it:

  * the load keeps climbing
  * I can still interact to some extent with running programs, but it
    seems HDD I/O has become impossible (`pwd` works, `ls` freezes the
    entire shell); can start some new commands, but many things
    freeze; can stop some programs, but some freeze when I try to
  * htop shows no out-of-control processes or such
  * powertop shows:
    - Intel and Cirrus codecs using 100% (`modprobe -r snd_hda_intel
      snd_hda_codec_cirrus` before or after suspend fixes this); seems
      like a result of the underlying problem instead of the cause
    - ~200 events/sec for blk_delay_work
  * `systemctl poweroff` fails w/ connection timeout
  * the only option availble to me is to turn off the power and reboot

I've had this problem before (at least the symptoms, I did not look at
powertop at the time), probably only twice over the past few months,
but never consistently like now.

Booting kernel 4.5.1-1 does not change anything.

I have another laptop (different make & model) which had the
intermittent version (again based on symptoms only) more frequently,
but apparently only if I had (dis)connected the AC power whilst it was
sleeping; never (dis)connecting AC power has so far made the problem
disappear, and that laptop does not experience this problem now
either.

Both laptops are running sid (equally up-to-date, mostly the same
packages).

I don't have a lot of time, but would be happy to do what I can to
help debug this (as not being able to use suspend is quite
bothersome).

P.S. I removed some information automatically added to the bugreport
that I considered probably unimportant and possibly bad for my
privacy.  If you really need this info, I'd be happy to provide it
directly, not publicly via the BTS.
