Strange crashes since Linux 2.0.31

[alex]

Hi!

I have a rather annoying problem. We run a a P166 with double 
Adaptec AHA-294X Ultra SCSI host adapters and 4 striped Quantum   Model:
XP34300W disks. It's been running fine on Linux 2.0.28, but I wanted to
try out 2.0.31. When I do this happends:

linux: scsi : aborting command due to timeout : pid 7447, scsi0, channel
0, id 0, lun 0 0x0a 02 40 63 04 00

If I switch off tagged queing, paged SCB:s it works but the machine gets
extremly slow and has a high load all the time. 2.0.28 is "standard"
configured, ie as it comes from the distribution. Anyone has any
suggestions ???
