hibernation problem after upgrade

Postby morgon » 2018-10-10 17:06

Hi,

I've recently upgraded my system (I am running testing) and now I have a problem with hibernation.

I usually bring the system down with "systemctrl hibernate". When I then turn on the PC again it resumes. This has worked without problems in the past.

Now I have kernel 4.18.6-1 and systemd 239-10 and I am having problems.

Sometimes it does work, but most of the time my system fails to resume. I often simply get a flickering monitor where I should get the lock-screen.

Any ideas?

Many thanks!

Does the systemd journal contain anything relevant when the problem occurs?

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=902416, perhaps?

That bug looks different.

I have the same versions on my laptop where (so far) I have not seen any problems.

I've seen some bluetooth-related stuff in the log and have now unpluged my (extremly cheap) bluetooth usb-dongle, and the next hibernation/resume cycle worked.

Could a crappy usb-bluetooth device (that works - I use it to stream music to my headphones) cause hibernation-problems?

Posting the verbatim log (with code tags) is always better than a vague description, perhaps we will see something you have missed.

EDIT: you put the errors in a search engine, right?
