Hi,

I was trying to port the pmap module from netbsd
current to an earlier version of netbsd. I am getting
a dsi...

trap type 300 at 5b13b20, Machine Status (SRR1)
0x00001032
DAR: 0xfe800030 DSISR: 0x40000000

the instruction at 5b13b20 is a load
5b13b1c:       39 00 00 00     li      r8,0
 5b13b20:       81 6a 00 30     lwz     r11,48(r10)

but r10+48 does not add up to 0xfe800030 (DAR)

db> show registers
r0           0x5a2c910  cpu_panic+0xb8
r1           0x5ba3960  end+0x89e8

r15                0x1

r20                  0
r21                  0

am I missing something? where did this EA 0xfe800030
come from?

I am running netbsd on 750 powerpc

any help is greatly appreciated...
