I've seen that type of behavior since kernel 0.99.10 with the soon-to-be-
replaced-by-either-Adaptec-or-BusLogic UltraStor controller I have. It's
gotten better over the past 2 years or so, and replacing the Syquest drive
I had with a Zip drive helped tremendously as well; the hardware in the
Syquest drive wasn't up to snuff, I guess. It still happens on occasion,
though, especially under load.
