I have an AHA-2930U2 SCSI card in a machine running the 2.2.14 kernel
with no driver patches. There are three devices on the bus - an
internal CD writer (Yamaha CDRW-6416S), an external 250Mb Zip, and an
external Minolta Dimage Scan Dual film scanner. The card and all three
devices work fine together under Windows. I upgraded to this card when
I bought the CD-RW as my previous card did not have an internal
connector (it was an AVA-2904, I think...). The Zip drive worked fine
with that card. However, when using Linux, none of them work - even if
all other devices are removed from the bus. If I try to mount a zip
disc, I get errors about bus timeouts (shown later). The machine then
begins to lock up for a few seconds every couple of minutes. I also get
huge numbers of interrupts - often up to 10,000 per second.
Here are some of the files in /proc, and some error messages. Let me
know if anything else would be useful (sorry there's so much in this
message)...

In 2-3 minutes, that makes 408,126 interrupts. As I said, it's often
much higher.

on.
