While booting a new kernel I built using NetBSD-current 1.1A. I got the 
following:

backplane0: (root)
cpu0 at backplane0: MicroVAX II
sbi0 at backplane0: Q22
uba0 at sbi0 tr0
uba0 at uba0 csr 172150 vec 20000004164, ipl 17
no vmspace in fault
TRAP: type 8 code 64, pc 8007b544, psl 4
P0BR 80000000 P1BR 80000000 P0LR  0 P1LR 200000
KSP  8009afcc ISP  8018f400 USP   0 
R0          0 R1          1 R2   805f1800 R3 84078000
R4   8009afb0 R5          0
(some garbage)
panic: trap at 65

I would like to know what I did to cause this.  I've used the GENERIC
config file to build a kernel with out a problem.  I've included the 
config file that I used to build the kernel that paniced.  Here it is:
