Hi all,

There seems to be a major problem with the promise drivers.
It is detected and seems to work, but there is a very 
large number of interrupts being generated:

adamm@polaris:/proc$ cat interrupts
           CPU0       CPU1
  0:    2727665    2683676    IO-APIC-edge  timer
  1:          1          1    IO-APIC-edge  keyboard
  2:          0          0          XT-PIC  cascade
  5:    1137650    1130539   IO-APIC-level  eth0
  7:          0          0    IO-APIC-edge  soundblaster
  8:       1812       1790    IO-APIC-edge  rtc
  9:     711977     709641   IO-APIC-level  sym53c8xx, eth1
 10: 2097584287 2097514818   IO-APIC-level  ide2, ide3
NMI:          0          0
LOC:    5411428    5411427
ERR:          0
MIS:       3013

adamm@polaris:/proc$ uptime
 12:57:30 up 15:01,  1 user,  load average: 0.36, 0.35, 0.40

Or a staggering ~40000 interrupts per second!

This is a dual PPro machine and it is using 30% cpu time
just to handle the interrupts.

Anyone know what is going on?

Thanks,
Adam
