My network driver is crashing an SMP system. CPU #1 is the first
to crash, with my driver on the stack. CPU #0 then crashes slightly
later (I'm assuming its collateral damage).
When I attach via remote-kdb, I see the stack from CPU #1, presumably
since it was the last to crash.
Is there a way to switch to cpu #0 so I can see the stack there?
Failing that, is there any easy way to disable the second CPU via
software? (like a boot arg, or something in OpenFirmware..)
FWIW, I'm using the binary kernel that comes with 10.2, so most of the
gdb macros seem useless... :(
Thanks,
Drew
