What I've noticed: * It only affects drives/filesystems attached via a SATA card * It occurs with SI 3113 or Promise 20575 SATA controllers, maybe others * The error starts under heavy file system load (What I usually do to trigger it is to start a file system copy of several gigs worth of files from a drive attached to the SATA controller to another drive on the motherboard bus (Via 8235). Sometimes this copy alone will trigger it. But its much more likely if I start some other read operation on the drive, like 'ls -lR' or a $ 'wc `find . -type file`) * it is reproducable based upon my own experience with it, I'd say that the following three bugs may be the same thing: kern/91410 kern/91408 i386/86364 Soren, I think this is your domain. Since it's fairly reproducible, let me know what I can do to help you find it. E: thede@loder.com
