Adding linux-ide and linux-scsi as CC like Andrew did with my last report. I still have trouble with my Silicon Image, Inc. SiI 3132 Serial ATA Raid II Controller as reported on 2.6.23-rc4-mm1 on the new 2.6.23-rc6-mm1. I'm not 100% sure if this caused by the sg chaining, but the patch from http://lkml.org/lkml/2007/9/10/251 which touches that chaining makes a difference, so it might be related. First report: http://lkml.org/lkml/2007/9/1/92 With patch it fails fewer times: http://lkml.org/lkml/2007/9/14/107 To update the statistik: prior to 2.6.23-rc4-mm1: no trouble with any drives on the SiI 3132. 2.6.23-rc4-mm1 without patch: 2 out of 2 bad. back to 2.6.23-rc3-mm1: 18x good. 2.6.23-rc4-mm1 with patch: 2 out of 8 bad after that second mail: 2.6.23-rc4-mm1 with patch: 1 out of 5 bad 2.6.23-rc6-mm1: 1 out of 2 bad 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.
