I am running Gentoo with a fresh 2.6.11-r1. I have all the kernel
debugging options turned on. Occasionally, I can get past the boot
process, but half the time it freezes somewhere along the way. If
not, I do get to boot, it doesn't take very long for it to freeze.
Any suggestions for how this can be debugged further?
other keywords: PowerPC, ppc, ppc64, Apple, freeze, freezing,
freezes, hang, hangs, froze, frozen, locks up, locked up, hard lock.

Did 2.6.10 work Ok? Try the patch below, it fixes 2.6.11-rc1 boot
lockups on both my Beige G3 (locks up in ADB driver) and my G4 eMac
(locks up in radeonfb).

The patch below works. Thanks.
