New kernel, new panic, new info:
db> witness_list
"Giant" (0xc0279be0) locked at ../../i386/isa/ithread.c:191
db> show registers
cs 0x8
ds 0x10
es 0x10
fs 0x18
ss 0x10
eax 0xdeadc0de
ecx 0xc59eb4b4
edx 0xc0279be0 Giant
ebx 0xc0a7a480 _end+0x36f8
esp 0xc65faf68
ebp 0xc65faf78
esi 0xc0a7a4e0 _end+0x3758
edi 0xc01fc998 ithd_loop
eax 0xdeadc0de
efl 0x10282
Besides the obvious need to fix this one problem, shouldn't we
ASSERT ih->ih_handler != NULL before calling it?
Bye,
Andrea
