Hi,

while installing a built release to / a -current NetBSD/i386 system
running a GENERIC 4.99.5 kernel paniced:

panic: lockmgr: locking against myself
Stopped in pid 1638.1 (nbpax) at	netbsd:cpu_Debugger+0x4:	popl	%ebp

(gdb) target kcore netbsd.1.core

Output of `ident /netbsd | sort' is [1]available. In case anybody is
interested I could also make the crash dump available.
