I'm in the middle of retiring nearly a dozen supermicro socket AM2 boards with this chipset. With the SATA controllers in native SATA mode the disks get scribbled on horribly. With the SATA controllers in legacy mode FreeBSD detects them as ATA/33 but they seem to hold up a bit better. Under heavy I/O load they will stay up for about a week before panicing, although once they do panic they double panic and hang solid. I thought I was going dodge swapping platforms by installing 3ware 9550 RAID controllers but I all I managed to do was reduce the panic rate to about once per month per box, so there are gremlins that affect more than the onboard SATA I'm afraid. I've attempted to work with at least one FreeBSD developer on a fix, but the inability of the boxes to complete a panic, let alone write a crash dump has made troubleshooting them incredibly painful. (Sometimes they don't even manage to get the entire first line of the panic string on the console) The fact that they will stand up for days under heavy I/O load doesn't help either. Intermittant problems suck. -- Thanks, Josh Paetzel PGP: 8A48 EF36 5E9F 4EDA 5A8C 11B4 26F9 01F1 27AF AECB
