For me it looks like ATA bug, as if I recall correctly various controllers from various vendors are affected. Unfortunately Soren isn't very active lately. As a work-around you may try disabling write cache on your disks (hw.ata.wc=3D0 to /boot/loader.conf), but this may only help to mitigate the problem. --=20 Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
