I saw the announcement for zfs v28 so I updated an ultra60
to the top of the tree. a 'zfs list' or 'zpool status' or 'kldload zfs'
will hang my machine.
I can break to the debugger via the serial console after I enabled
the alternate break sequence.
Has anyone else tried the latest zfs with sparc64 machines ?=20
