Hello,
I was facing the issue above for quite some time now. Unfortunately up to
this point I was not able to capture any bug report. Just yesterday was the
first time I was able to see the bug reports and I was able to interrupt the
restart process because as soon as my system restarted all the bug reports
were gone. Anyway I am hoping you can use the information above to give me
an indication how I can prevent these crashes from happening as I am not
aware what causes them.
Thank you so much for any help you can provide.
Regards
Manuel

Hi
This bug was filed for a very old kernel or the bug is old itself
without resolution.
If you can reproduce it with
- the current version in unstable/testing
- the latest kernel from backports
please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.
Regards,
Salvatore
