jfs mount causes oops on sparc64

[Alex Deucher <alexdeucher@gmail.com>]

I have a 6.9 TB jfs LVM volume on a sparc64 debian box, however mount
seems to cause an oops when I attempt to mount the volume:

jfs_mount: diMount(ipaimap) failed w/rc = -5
data_access_exception: SFSR[0000000000801009] SFAR[000000000043f770], going.

kernel is 2.6.12rc3 on debian sparc.  Any ideas?
