>Description:
My machine had an uptime for about a day with a lot of zzz between
active session of using it. When I've restarted VM with alpine linux
to run docker it consume a lot of CPU by ungoogled-chrome and Xorg.
An attempt to close chrome leads to a crash with stack trace (I took
a photo and OCR it, so, text bellow may contains errors):

ddb{2}>
Anyway, it was the first crash, usually I was able to reboot machine
which helps. Kills X11 doesn't help. Nor rcctl restart vmd.
I've seen that issue for weeks, and it happens not on the first
start of VM, I need a few cycle during machine uptime. The last time
it had happened after reboot inside VM, not via vmctl.
I do use sync option with softraid with encryption of local disk,
and both VM drives is kept on such disks. The second drive is quite
large (100G), and the first one is realitly small (5G).
I run custom kernel with patche for powersave policy, anyway, I had
noticed that issues (CPU usage after start / restart of VM) on
original kernel as well.
>How-To-Repeat:
Restart VM multiple times.
>Fix:
I have no idea.
