Last week I reported a bug:
http://lists.ozlabs.org/pipermail/linuxppc-dev/2009-October/076727.html
I managed to drill past the unrelated breakage and bisect it back to the
relevant commit: It was introduced leading up to 2.6.29, by commit
f751928e0ddf54ea4fe5546f35e99efc5b5d9938 written by Alan Cox.
It seems to make the kernel panic as soon as IRQs are enabled in the presence
of CONFIG_SERIAL_PMACZILOG=y. It's trivially reproducible under current qemu-
git. Kernels before that boot to a shell prompt, kernels after that panic as
soon as init launches. (They work fine when you're not using a serial
console.)
