Booting a new kernel after "make installkernel"

[Bill Sorenson]

Hopefully this makes sense. What i want you to do is replace
"sys/dev/ofw/ofw_iicbus.c" in 10.3 with the "sys/dev/ofw/ofw_iicbus.c" from
10.2. There was a commit about 2 months ago to 10-stable and now 10.3 that
I think broke the way Open Firmware machines read temp sensors, so your
kernel wont boot because it thinks your system is overheating and resets.

If you check out 10.3 and copy the 10.2 ofw_iicbus.c over into the tree
replacing the newer one, I'll bet you'll build and boot fine.

If it solves your problem I'll know I'm on the right track. (I think the
breakage is actually in a driver somewhere, and the fix to ofw_iicbus.c
caused a regression).

Anyway, you should be able to just try building the kernel rather than the
whole system if you want to save time. Especially if your 10.3 userland
already booted back up with your kernel.old before.

Thanks,
Bill S.
