--- Comment #12 from Krautmaster <mathias.kraut@gmx.de> ---
this afternoon i booted Freebsd by fault after a short power issue and started
a larger copy again (geli drive to normal unencrypted one).

System was running without your provided patch and crashed again. This time
different again (like httpd and 2x geli)
Anyhow this makes me think that the quite common panics in 13 might have a same
root cause?

See the panic below.

Additionally, I was able to get a patched kernel up and running now and will
see if this is more stable in freeBSD 13.1
