The machine is x86_64 SMP. I also got the oops in the Fedora kernels:
2.6.20-1.2933.fc6 and 2.6.20-1.3017.fc7. The system isn't locked solid but
it seems anything touching the scsi disks hangs. I also twice got this early
in the boot and it stopped booting.
Anything I can do to help just ask.

I'm having little hangs while booting with kernels 2.6.12 and 2.6.13-rc1, rc2

It is strange that 2.6.12-rc1 booted ok without hangs.
Hangs appears just before mounting filesystems message and before configuring
system to use udev.
