Well, Thursday's world seems to have broken ATA in a new and interesting way. Before updating world in mid-September, my drive ran perfectly in UDMA66 mode. Since that time, the system is absolutely guaranteed to freeze if I run in any mode higher than BIOSPIO. Before two days ago, that meant getting errors like: ad0: TIMEOUT - WRITE_DMA retrying (2 reties left) ata0: resetting devices ad0: FAILURE - already active DMA on this device ad0: setting up DMA failed before infinite, unbreakable hangs. As of today, when running in any DMA mode and exercising the ATA system, I get an endless stream of messages: swap pager: indefinite wait buffer and I can only break out of the error cycle with a reset. For the record, I've checked the cabling multiple times. "smartctl" gives good results. The machine runs perfectly under FreeBSD 4.9 or versions of 5.x prior to mid-September. Any thoughts before I file (another) PR?
