That driver has been undergoing some work from what I see in the kernels ChangeLog (I don't use it myself, my card is an advansys, bulletproof) and if he has the aic7xxx.old driver available, maybe he should give that one a try. My kernel is 2.4.21, and I don't recall if both drivers are still available or not. That would be my next suggestion, that he move on up to a newer kernel, thereby getting the latest code. And since this is scsi we're talking about here, the goat must be pure white and a virgin. Not to mention that in a scsi setup, the last device on the cable must be on the last plug on the cable. A few inches of open cable past the device will make nearly all bets instant losers. Then of course it doesn't matter what color the goat was, the spell is broken... :) -- Cheers, Gene AMD [EMAIL PROTECTED] 320M [EMAIL PROTECTED] 512M 99.26% setiathome rank, not too shabby for a WV hillbilly Yahoo.com attornies please note, additions to this message by Gene Heskett are: Copyright 2003 by Maurice Eugene Heskett, all rights reserved.
