I am using a supermicro sat2-mv8 pcix controller, which has a marvell 88sx6081 controller. Every few hours, the machine hangs, and I have to power cycle it. I build a kernel with debugging enabled, version 2.6.30.5 Here are the last few messages from syslog. I suspect they are from the ata layer. I would appreciate any advise. jeff Sep 8 09:13:26 sata_fileserver klogd: ata8: exception Emask 0x10 SAct 0x0 SErr 0x180000 action 0x6 frozen Sep 8 09:13:26 sata_fileserver klogd: ata8: edma_err_cause=02000020 pp_flags=00000003, SError=00180000 Sep 8 09:13:26 sata_fileserver klogd: ata8: SError: { 10B8B Dispar } Sep 8 09:13:26 sata_fileserver klogd: ata8: hard resetting link Sep 8 09:13:26 sata_fileserver klogd: ata3: exception Emask 0x10 SAct 0x0 SErr 0x100000 action 0x6 frozen Sep 8 09:13:26 sata_fileserver klogd: ata3: edma_err_cause=02000020 pp_flags=00000003, SError=00100000 Sep 8 09:13:26 sata_fileserver klogd: ata3: SError: { Dispar } Sep 8 09:13:26 sata_fileserver klogd: ata3: hard resetting link Sep 8 09:13:26 sata_fileserver klogd: ata5: exception Emask 0x10 SAct 0x0 SErr 0x100000 action 0x6 frozen Sep 8 09:13:26 sata_fileserver klogd: ata5: edma_err_cause=02000020 pp_flags=00000003, SError=00100000 Sep 8 09:13:26 sata_fileserver klogd: ata5: SError: { Dispar } Sep 8 09:13:26 sata_fileserver klogd: ata5: hard resetting link Sep 8 09:13:26 sata_fileserver klogd: ata7: exception Emask 0x10 SAct 0x0 SErr 0x100000 action 0x6 frozen Sep 8 09:13:26 sata_fileserver klogd: ata7: edma_err_cause=02000020 pp_flags=00000003, SError=00100000 Sep 8 09:13:26 sata_fileserver klogd: ata7: SError: { Dispar } Sep 8 09:13:26 sata_fileserver klogd: ata7: hard resetting link Sep 8 09:13:26 sata_fileserver klogd: ata3: SATA link up 3.0 Gbps (SStatus 123 SControl 300) Sep 8 09:13:26 sata_fileserver klogd: ata8: SATA link up 3.0 Gbps (SStatus 123 SControl 300) Sep 8 09:13:26 sata_fileserver klogd: ata8.00: failed to IDENTIFY (I/O error, err_mask=0x40) Sep 8 09:13:26 sata_fileserver klogd: ata8.00: revalidation failed (errno=-5) Sep 8 09:13:27 sata_fileserver klogd: ata3.00: configured for UDMA/133 Sep 8 09:13:27 sata_fileserver klogd: ata3: EH complete Sep 8 09:13:27 sata_fileserver klogd: ata5: SATA link up 3.0 Gbps (SStatus 123 SControl 300) Sep 8 09:13:27 sata_fileserver klogd: ata7: SATA link up 3.0 Gbps (SStatus 123 SControl 300) Sep 8 09:13:27 sata_fileserver klogd: ata7.00: configured for UDMA/133 Sep 8 09:13:27 sata_fileserver klogd: ata7: EH complete Sep 8 09:13:27 sata_fileserver klogd: ata5.00: configured for UDMA/133 Sep 8 09:13:27 sata_fileserver klogd: ata5: EH complete Sep 8 09:13:31 sata_fileserver klogd: ata8: hard resetting link Sep 8 09:13:32 sata_fileserver klogd: ata8: SATA link up 3.0 Gbps (SStatus 123 SControl 300) Sep 8 09:13:32 sata_fileserver klogd: ata8.00: configured for UDMA/133 Sep 8 09:13:32 sata_fileserver klogd: ata8: exception Emask 0x10 SAct 0x0 SErr 0x0 action 0x1 t4 Sep 8 09:13:32 sata_fileserver klogd: ata8: edma_err_cause=00000020 pp_flags=00000000, SError=00080000 Sep 8 09:13:32 sata_fileserver klogd: ata8.00: configured for UDMA/133 Sep 8 09:13:32 sata_fileserver klogd: ata8: EH complete Sep 8 09:21:34 sata_fileserver syslogd 1.5.0: restart.
