Here is as much information as I could get. After upgrading to a
snapshot earlier today (October 25th), the Exoscale VPS panics on boot.
I use this VPS to self-host synapse (a Matrix homeserver, for
messaging).
I can't copy and paste from the web console that Exoscale provides so I
had to transcribe all of it by hand, I hope it's all accurate. In
particular, the correct number of spaces between fields in `ps` output
is unknown to me, but everything else should be OK I think. I tried to
get a traceback for cpu1 as well, but the console hangs when I issue
`machine ddbcpu 1` so only the traceback for cpu0 was available to me.
Booting /bsd.sp instead of /bsd.mp or scaling the VPS down to one core
appears to make no difference, the panic happens regardless.
Any suggestions to get my VPS back up and running would be much
appreciated, I feel pretty lost with what to do next. Thanks.
