The ROSB4 is known to have data-corruption problems with running in UDMA mode. The dump is probably tripping over this, which is why Tor's patch works since it demotes the device back to PIO. You could optionally set hw.ata.ata_dma=0 in loader.conf to disable UDMA rather than apply the patch. -- Doug White | FreeBSD: The Power to Serve dwhite_at_gumbysoft.com | www.FreeBSD.orgReceived on Tue Oct 07 2003 - 16:11:31 UTC
