System boots fine with linux-image-2.6.32-3-mckinley 2.6.32-9.
Panics with 2.6.32-20 with: I/O MMU @ c0000000fed01000 is out of

fyi, my rx2600 boots fine on both 2.6.32-20 and 2.6.32-21.
(ROM Version 2.31)

This was a zx2000, same ROM, and I was about to try a rx2600. I
guess this makes it moot ;P

Just thinking out loud, but given the symptoms (disk errors) and the
specifics of zx2000 vs rx2600, I'm guessing the IOMMU pukes on IDE,
which rx2600 doesn't use for disks...

That might be significant, since we've made the libata transition.
Did you get a traceback for the kernel panic?

Another datapoint - also was unable to reproduce on a zx2000 here,
though mine uses contains only SCSI disks.

Well then, looks like you've got the culprit (IDE)...
