[ECOS] Crashing on MPC823FADS in hal_IRQ_init

[Kenneth Porter]

I'm trying to bring up a test on my FADS system just to verify that
something is working.

I cvs'd the latest eCos, built a FADS/RAM library and test cases, and
tried running the smallest kernel test case (thread0.exe). I downloaded
it with mpc8bug and it crashes in hal_IRQ_init with:

exception: Implementation Specific Data TLB miss
.L420+0x8         0x00009fb8    80090000 lwz    r0, 0x0(r9)

r9 at this point contains 0xff000014. I'm not sure but I think this is
in the switch in the unmask routine.

BTW, anyone get gdb to talk to a FADS? How did you do it? I'm trying to
get it to talk to MPC8BUG but MPC8BUG whines about packet CRC errors
when gdb starts to download the load image.
