'k, can you see what happens if you do:

gdb -k kernel.debug vmcore.0

?

I get:

This GDB was configured as "i386-undermydesk-freebsd"...(no debugging symbo=
ls found)...
panic: page fault
panic messages:
---
dmesg: kernel message buffer has different magic number
---
---Can't read userspace from dump, or kernel process---

#0  0xc022dc1e in dumpsys ()

but don't know if its because I'm on a 5.x system or if the crash is
corrupted :(
