	Hello,

	New panic last night...

1 tt=30 tstate=4411001505 tpc=0x1001488 tnpc=0x100148c
2 tt=30 tstate=4482000603 tpc=0x12e1da0 tnpc=0x12e1da4

Debug information :

0x12e1da0 is in mutex_vector_enter (/usr/src/sys/kern/kern_mutex.c:440).

	You can see that this panic is exactly the same than last panic.
