I'm certain that the issue with this card isn't limited to ZFS. It's been seen before in the 6.x series too. I really would like to find out which code changes ruined the card's correct operation... if that could help the ata maintainer in some way. Unfortunately my csup-fu isn't that strong, otherwise I would send my source tree back to June 15th and analyse daily buildworlds from that date until I could pin-point the exact date and file changes that caused the problem all of us are seeing. Could someone teach me how to do csup rollbacks to a specific date in the source tree? If it's not obvious already, I'd really like to squash this bug.
