We had very similiar problems with WD 100 GB (WD1000BB) disks on a 3ware controller. We'd get this error for no apparent reason: twe0: AEN: It turns out that there is some bios incompatability between the 3ware controller and these WD disks. Once I found the right person at 3ware and described my problem, he said that its the disks. We switched to IBM disks and the problem went away. I have NO IDEA if the problem is the same on the WD800BB disks. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
