OK, so this one is repeatable now, and it looks like an
interraction between the ramdisk driver and XFS.
2 way SMP 1400 with 1Gb memory,
SCSI disk.
t-o-t kernel, kio _not_ enabled.
setup:
mkfs -t xfs -f /dev/sdc5

==========================
=> XFS is not really part of the problem here, it is just triggering lots of
=> I/O.
That's just about where I got to yesterday. At first I was assuming it
was at fault, then I thought involved, now I suspect it's just a catalyst.
=> There appears to be a deadlock between the lru_list_lock and the
=> io_request_lock.
Under the circumstances, it's probably the ramdisk. I'll chase
this up with some relevant Linux people...
