2940U2W controller freezes several times a day for up to several minutes at a time. The system (single PII, 100Mhz ASUS P3B-F motherboard) still responds, but any requests to the drives hangs. It appears to happen mostly when the system is having a moderate or heavy load. I have now set Tagged Command Queueing on, with max 24 commands per device, reset delay at the default 5 seconds, but this has made no difference. The adapter only has a pair of matched Seagate Cheetah drives, attached via a short, internal LVD/SE cable that has a built-in terminator. I've tried a number of things, but without anything in the logs, I'm stumped. I've included the boot log below in the hopes that someone might see some problem. Thanks for any ideas and/or suggestions.
