Yes, but I'm unable to produce a crash dump  :-(
Tryed even with voodoo, added and removed options to
kernel (kdb, gdb, ddb, invariants, ...).  Instead of
going to db> now it panic-and-freeze with:

cpuid = 0
Uptime: 2m16s
panic: _mtx_lock_sleep: recursed on non-recursive mutex \
	mpt @ /usr/src/sys/cam/cam_periph.h:182

(above lines get repeated a lot with same uptime, then freeze)


Still trying other combinations...
