Hi everyone,

Just a heads up that after updating my FreeBSD 12-current machine to
r307773 I am still getting this kernel panic.

Note that I have compiled the kernel with VIMAGE support if that makes any
difference.

Mateusz: any further ideas on what it could be?

Any help is appreciated :)

Regards,
Ben
