Laptop hangs after wake up in stretch

[Tobias Bengfort <tobias.bengfort@posteo.de>]

Hi,

since updating to stretch I have a weird issue with my Lenovo X201
laptop: Sometimes when waking up from suspend it "hangs". The symptoms
are somewhat strange:

- All open programs still work fine.
- I can open a new tab inside of an existing terminal. The bash prompt
appears just fine.
- Any process I try to start hangs.
- The CPU monitor in lxpanel shows 100% usage.

I was not yet able to reliably reproduce the issue. I feel that it often
happens after suspending on battery power.

Has anyone ever experienced something similar? Any pointers as to where
I should look for clues?
