So these changes breaks libata or libata was broken after 2.6.23-rc3-mm1. Can you try Jens's sglist-arch branch? If it works, probably libata in -mm has bugs. For your convenience, I put a sglist-arch branch patch against v2.6.23-rc7: http://www.kernel.org/pub/linux/kernel/people/tomo/misc/v2.6.23-rc7-sglist-arch.diff.bz2 > switching back to 2.6.23-rc3-mm1 to rule out the hardware: > 2.6.23-rc3-mm1: 6x good > > The error messages from the failed 2.6.23-rc6-mm1: > Sep 18 18:50:01 treogen [ 33.340000] md1: bitmap initialized from > disk: read 10/10 pages, set 0 bits > Sep 18 18:50:01 treogen [ 33.340000] created bitmap (145 pages) for device md1 > Sep 18 18:50:01 treogen [ 63.440000] ata1.00: exception Emask 0x0 > SAct 0x1 SErr 0x0 action 0x6 frozen > Sep 18 18:50:01 treogen [ 63.440000] ata1.00: cmd > 61/08:00:09:d6:42/00:00:25:00:00/40 tag 0 cdb 0x0 data 4096 out > Sep 18 18:50:01 treogen [ 63.440000] res > 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) > Sep 18 18:50:01 treogen [ 63.440000] ata1.00: status: {DRDY } > Sep 18 18:50:01 treogen [ 63.440000] ata1: hard resetting link > Sep 18 18:50:01 treogen [ 65.740000] ata1: softreset failed (port not ready) > Sep 18 18:50:01 treogen [ 65.740000] ata1: reset failed (errno=-5), > retrying in 8 secs > Sep 18 18:50:01 treogen [ 73.440000] ata1: hard resetting link > Sep 18 18:50:01 treogen [ 75.740000] ata1: softreset failed (port not ready) > Sep 18 18:50:01 treogen [ 75.740000] ata1: reset failed (errno=-5), > retrying in 8 secs > Sep 18 18:50:01 treogen [ 83.440000] ata1: hard resetting link > Sep 18 18:50:01 treogen [ 85.740000] ata1: softreset failed (port not ready) > Sep 18 18:50:01 treogen [ 85.740000] ata1: reset failed (errno=-5), > retrying in 33 secs > Sep 18 18:50:01 treogen [ 118.440000] ata1: limiting SATA link speed > to 1.5 Gbps > Sep 18 18:50:01 treogen [ 118.440000] ata1: hard resetting link > Sep 18 18:50:01 treogen [ 120.740000] ata1: softreset failed (port not ready) > Sep 18 18:50:01 treogen [ 120.740000] ata1: reset failed, giving up > Sep 18 18:50:01 treogen [ 120.740000] ata1.00: disabled > Sep 18 18:50:01 treogen [ 120.740000] ata1: EH complete > Sep 18 18:50:01 treogen [ 120.740000] sd 0:0:0:0: [sda] Result: > hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK,SUGGEST_OK > Sep 18 18:50:01 treogen [ 120.740000] end_request: I/O error, dev > sda, sector 625137161 > Sep 18 18:50:01 treogen [ 120.740000] md: super_written gets > error=-5, uptodate=0 > Sep 18 18:50:01 treogen [ 120.740000] raid5: Disk failure on sda2, > disabling device.
