cause of EXC_MCHK (0x200) "Machine Check" is PPC implementation-specific.
for 7400, 7410 it would be useful if trap() shows the value in SRR1;
for 7450 (and 7451) I think there is another register MSSSR0
that captures the cause.  

we have seen these on G4's where SRR1 indicates 
TEA "Transaction Error Acknowledge" -- basically a bus error.
Smells like flakey HW?

Subject: Kernel Panic


Hello, whenever I try to compile a GENERIC current kernel, it panics...

trap type 200 at 308e6c
Press a key to panic.
panic: trap
Stopped in pid 0 () at    0x2fdf70:     lwz     r0, r1, 0x14,
db>


It is froze at this point, my keyboard does not work, that might be
because I have a new iBook and it has that ihandle problem, so I use a
external USB keyboard, and it hasn't been intialized. Any suggestions
would be greatly appreciated. Also is there any way to have it so the
console has a black background and white foreground?
