But I get lots of ata exceptions and the kernel eventually slows down my drive to UDMA/33. It usually happens on ata1 (sda), but sometimes it'll kick in on ata2 (sd= b). I can definitely cause this to happen more by increasing load on the disk= s. But even low load (checking email) causes this. Full hardware and softwar= e specs are below, but first, the errors: ata1.00: exception Emask 0x10 SAct 0x0 SErr 0x180100 action 0x2 ata1.00: cmd c8/00:d0:8a:31:ae/00:00:00:00:00/e0 tag 0 cdb 0x0 data 10649= 6 in res 51/0c:0f:4b:32:ae/00:00:00:00:00/e0 Emask 0x10 (ATA bus erro= r) ata1: soft resetting port ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata1.00: configured for UDMA/133 ata1: EH complete SCSI device sda: 312581808 512-byte hdwr sectors (160042 MB) sda: Write Protect is off sda: Mode Sense: 00 3a 00 00 SCSI device sda: write cache: enabled, read cache: enabled, doesn't suppo= rt DPO or FUA ata1.00: exception Emask 0x10 SAct 0x0 SErr 0x380100 action 0x2 ata1.00: cmd c8/00:a0:12:fa:bc/00:00:00:00:00/e0 tag 0 cdb 0x0 data 81920= in res 51/0c:1f:93:fa:bc/00:00:00:00:00/e0 Emask 0x10 (ATA bus erro= r) ata1: soft resetting port ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata1.00: configured for UDMA/133 ata1: EH complete SCSI device sda: 312581808 512-byte hdwr sectors (160042 MB) sda: Write Protect is off sda: Mode Sense: 00 3a 00 00 SCSI device sda: write cache: enabled, read cache: enabled, doesn't suppo= rt DPO or FUA ata1.00: limiting speed to UDMA/100 ata1.00: exception Emask 0x10 SAct 0x0 SErr 0x380100 action 0x2 ata1.00: cmd c8/00:48:2a:27:ac/00:00:00:00:00/e0 tag 0 cdb 0x0 data 36864= in res 51/0c:27:4b:27:ac/00:00:00:00:00/e0 Emask 0x10 (ATA bus erro= r) ata1: soft resetting port ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata1.00: configured for UDMA/100 ata1: EH complete SCSI device sda: 312581808 512-byte hdwr sectors (160042 MB) sda: Write Protect is off sda: Mode Sense: 00 3a 00 00 SCSI device sda: write cache: enabled, read cache: enabled, doesn't suppo= rt DPO or FUA ata1.00: limiting speed to UDMA/66 ata1.00: exception Emask 0x10 SAct 0x0 SErr 0x180100 action 0x2 ata1.00: cmd c8/00:f8:6a:7a:ae/00:00:00:00:00/e0 tag 0 cdb 0x0 data 12697= 6 in res 51/0c:97:cb:7a:ae/00:00:00:00:00/e0 Emask 0x10 (ATA bus erro= r) ata1: soft resetting port ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata1.00: configured for UDMA/66 ata1: EH complete SCSI device sda: 312581808 512-byte hdwr sectors (160042 MB) sda: Write Protect is off sda: Mode Sense: 00 3a 00 00 SCSI device sda: write cache: enabled, read cache: enabled, doesn't suppo= rt DPO or FUA Kernel: 2.6.20.6 (PREEMT & SMP) SATA Controller: 02:04.0 RAID bus controller: Promise Technology, Inc.

The sata drives and cables are fresh out of the box.
