After grinding away for a few hours, I get: kernel: ad6: WARNING - SETFEATURES SET TRANSFER MODE taskqueue timeout - completing request directly 1 hour 4 minutes later it rebooted, and did not cleanly unmount the filesystems. (any of them, not just the ones on ad6) No panic message found anywhere. I haven't seen this message before, this disk has been running fine for about 7 months. What exactly does this warning message mean? Shouldn't I have gotten a panic message? Assuming that the kernel decided to reboot without unmounting the ad6 filesystems, why didn't it at least sync/unmount the filesystems on other disks? Did it decide to not trust the controller, or perhaps itself?
