--- Comment #2 from Oleg Cherkasov <***@linux.com> ---
Created attachment 211408
--> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=211408&action=edit
new panic around day after

11.3-RELEASE-p5

The stack trace slightly different.

Still not sure why it does not dump to swap. The swap is 24G so it is enough
for minidumps. Does it mean the kernel lost ada0 device with all partitions on
panic?
