I've been playing with it for a few days and I couldn't get to work reliably in anything but 2.6.22-rc5. Now that I use 2.6.22-rc5, I get those errors for a few minutes then the driver hard resets and locks at 1.5 Gb/s. It seems reliable after that but I do get those errors every now and then under heavy I/O. I read in another thread by a developer those errors are handled and no loss of data was occuring, they make me uneasy though. After a fresh reboot, I get these errors for a while: Jun 19 13:28:15 phoenix ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 Jun 19 13:28:15 phoenix ata2.00: (port_status 0x20080000) Jun 19

Gb/s, it stays quiet for a while until periods of extremely heavy I/O. In previous kernel versions, they would lower DMA modes until they reached PIO. I'd rather resync to 1.5 Gb/s than be in PIO mode, though I would prefer to have a 3.0 Gb/s link and no errors at all. SMART reports no drive errors (they are all brand new, as is the controller). During heavy I/O, I will see these messages: Jun 19 21:25:16 phoenix ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 Jun 19 21:25:16 phoenix ata2.00: (port_status 0x20080000) Jun 19 21:25:16 phoenix ata2.00: cmd c8/00:80:3f:12:52/00:00:00:00:00/e0 tag 0 cdb 0x0 data 65536 in Jun 19 21:25:16 phoenix res 50/00:00:be:12:52/00:00:00:00:00/e0 Emask 0x2 (HSM violation) Jun 19 21:25:16 phoenix ata2: soft resetting port Jun 19 21:25:16 phoenix ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 310) Jun 19 21:25:16 phoenix ata2.00: ata_hpa_resize 1: sectors = 781422768, hpa_sectors = 781422768 Jun 19 21:25:16 phoenix ata2.00: ata_hpa_resize 1: sectors = 781422768, hpa_sectors = 781422768 Jun 19 21:25:16 phoenix ata2.00: configured for UDMA/133 Jun 19 21:25:16 phoenix ata2: EH complete Jun 19 21:25:16 phoenix sd 1:0:0:0: [sdb] 781422768 512-byte hardware sectors (400088 MB) Jun 19 21:25:16 phoenix sd 1:0:0:0: [sdb] Write Protect is off Jun 19 21:25:16 phoenix sd 1:0:0:0: [sdb] Mode Sense: 00 3a 00 00 Jun 19 21:25:16 phoenix sd 1:0:0:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA I'd really like to see this working in 3.0 Gb/s without any errors and I'd be more than happy to help test any possibly solutions. I'm guessing the root of this issue lies in libata or some implementation of sata_promise. I hope this helps someone, I've been searching for days. - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
