I'm not sure what SCSI controller you're using. Could it be : that your controller is corrupting data when it is "very" busy? That's crap. Pure crap. The 1522's maybe, but not the 1542. They have a good DMA architecture. There may be a bug in the 1542 driver for FreeBSD, but it isn't the fault of the cards. And if there is a bug, I'd like to know how to recreate it so I can fix it... Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
