You say you reverted to a previous kernel - I presume you managed to
recover the filesystem using this kernel. If so, what was the 'previous'
kernel? Have you run recovery on sparc64 systems before?
I have seen this trace in a crash before, but not for quite a while,
I will have to think about this one a little.
