--- Comment #32 from Lev A. Serebryakov <lev at FreeBSD.org> ---
I've removed KDB_UNATTENDED from kernel and got dump! Looks like kernel memory
is complete mess at this moment, as it panics on all 4 cores!



Unread portion of the kernel message buffer:
kernel trap 9 with interrupts disabled
kernel trap 9 with interrupts disabled
