I just bought a BusLogic 948 PCI, the one that does ultra-narrow 20MB/sec.
Whenever I do a lot of reading/writing the SCSI card timeout, and the kernel
has to reset the scsi bus. My box is a P5-90 with 80 megs of RAM, and the
buslogic card is only connected to a 1 gig Seagate ultra scsi disk. I am
running Linux 2.0.29.
Any ideas on why this happens and/or how to fix it? Should I have bought
the AHA 2940U instead?
There are many possible reasons for timeout/reset problems with Ultra SCSI
devices. Which Seagate disk is this? If this is a Seagate Hawk drive, there
was a BT-948 firmware bug that was corrected several months ago which could
lead to symptoms like you report. The corrected firmware is available from my
Linux Web Page (http://www.dandelion.com/Linux/). Please send me a copy of the
SCSI subsystem and BusLogic driver messages, and I'll have a better idea what
to suggest.
