Attach any IDE hard disk (regardless if it's U-33/66 or whatever)
to your HPT 366
and then access that disk and any SCSI device at the same time -
I'd be surprised
if you won't experience a lockup...
Of course, I meant "...doesn't need an IRQ if you _do_ use HPT
366. If you don't,
you might be all right."
I did have reproducible lockups when my Hauppauge WinTV was in
slot 3 _immediately_
after issuing any "mount /dev/hde1 ..." command, but of course
only while watching TV.
All windows froze, the mouse cursor showed no reaction, I couldn't
move around the
virtual screen, no reaction to any key or key combination, I
couldn't rlogin or
telnet to the box - but the TV program's sound continued
"happily". I doubt the system
was totally "dead", but at least it was totally uncontrollable,
leaving me only the
"Reset" or "Power Off" button as choice :-(.
But all that happened only after a few hours uptime and with small
/ moderate load,
so I doubt that phenomenon is similar to the reported locks after
days or even weeks
of uptime during heavy load. I never met such locks again, but I
haven't run the box
more than, say, 14 hours a time and not exceeded a load of ~3.5
yet - and this only for
short time, though.
I stick to say linux can't handle IRQ sharing with BP6 (yet), at
least not if one of
the devices is HPT 366.
Anyone please feel free to correct me if I'm wrong...
