True, but I think Alan Cox mentioned something about new code setting 
pio4 and udma6
at the same time so I was hoping new code might relate to system hangs 
on mkfs, fsck,
cp to raid on commodity-promise-controlled drives. I might try the lba48 
patch on a
null-modem serial setup in case there's other code in there. I could use 
a promise
sx-6000 according to Oliver Pitzeier oliver@linux-kernel.at (see below) 
but that's
an expensive onboard raid card, not commodity booty using linux software 
raid.
Lost time moots the expense issue but commodity servers need a cheap 
reliable controller
card, a tulip equivalent in the controller card category, to make a 
cheap net-speed
file-server.

As I always tell my customers: Promise means trouble; At least within Linux.

The only Promise controller that works fine for me is a SX-6000 with 6 drives (raid-5, 1 spare).

Best regards,
 Oliver
