Bug#823356: linux-image-4.5.0-2-amd64: system freezes (HDD I/O seems impossible, load keeps climbing) after suspend
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).
- Felix
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.
