Title:
Kernel panic with Strongswan IPSec vpn after 20.4 update
Status in linux package in Ubuntu:
Incomplete
Bug description:
I have a Strongswan (Linux strongSwan U5.8.2/K5.4.0-54-generic) IPSec setup
and whenever I connect to it the connection is estabilished succesfully, but
when I try to reach anything on the network the server freezes with kernel
panic. The problem appeared when I upgraded from 18.04 to 20.04
After reboot I can't find anything in the log, so it's a bit hard to gather
the kernel message, the only thing I have saved is this line:
general protection fault: 0000 [#1] SMP PTI
End of the strongswan log:
