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?

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).
