I'm running RELENG_6 on two machines, one SMP and one UP (both using = SCHED_4BSD). I cvsup/update the OS a few times a week, and after an = update on Saturday (24/9) I've seen multiple "TIMEOUT - READ_DMA48 = retrying" errors on both machines, causing all sorts of trouble (broken = arrays, panics, ...). After a reboot the disks have come back to life = and seem to work just fine. It could just be a coincidence and multiple disks on two separate = machines have started to go bad, but since the disks are different = models on different ATA/SATA controllers in different machines it could = also be an indication that something has happened with FBSD. If it's a = FBSD problem then the "offending" code was added some time between = Monday 19/9 and Saturday 24/9. Is anyone else experiencing similar problems? /Daniel Eriksson
