[ delete descriptions of hang symptoms ]
Stuart,
All your symptoms point at disk IO hanging.
Setting the default queue depth to 1 would be worth trying.
I've forgotten the details for setting queue depth.
search parisc-linux mailing list archives "scsi queue tags".
http://lists.parisc-linux.org/pipermail/parisc-linux/2004-January/022087.html
btw, 715/50 is NOT the same as 715/100.
715/100 should have "coherent" DMA and 715/50 does not.
Maybe a FAQ entry for "715/xxx hangs" could be your first contribution?
hth,
grant
