When I purchased my PIII/933 on an ASUS CUSL2-C board, the system would hang hard. During most of the hangs the LED connected to the AHA-2940UW was lit. I was able to reproduce the hang 1 out of every 3 by using the external SCSI Zip-100 drive, though I/O to other devices on the SCSI bus would hang the system too (not as reproducible as I/O to the Zip drive). I discovered a web page at scsifaq.org that claimed that the 2940 and 100 MHz FSB (the CUSL2-C has a 133 MHz FSB) were incompatible, causing hard hangs, leading me to consider this a PCI problem. Disabling PCI 2.1 (reverting to PCI 2.0) in the BIOS solved the problem, no hangs since.
