XFS behaves better with sym2+MMIO on j6000 running a 64-bit SMP kernel.
I was able to run spew several hours with no problems.
This is without the patch that Joel pointed out from the -mm tree.

This suggests there is a problem with Astro/Elroy programming
where "Sprockets" firmware (for Astro based workstations) does
something different than PAT PDC firmware on a500.
I'm investigating.


However, did see one "WARN_ON" when I rsync (/home to /home2):
root@gggj6k:/home# df

The rsync completed but one error showed up 4 times on the console
during the second half (about) of the rsync:

Perhaps this is fixed in the patches; I haven't looked.
