I'm running 2.6.18.1 with the patches from http://home-tj.org/wiki/index.php/Libata-tj-stable since I was not able to get the port multipler to work at all with 2.6.21 (perhaps the support for PMP is not fully integrated there). One of my Sil3726 is freezing my system approx one time per hour when the disks are under load. ata5.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen ata5.00: tag 0 cmd 0xea Emask 0x4 stat 0x40 err 0x0 (timeout) ata5.15: hard resetting port ata5.15: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata5.00: hard resetting port ata5.00: SATA link up 3.0 Gbps (SStatus 113 SControl 300) ata5.01: hard resetting port ata5.01: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata5.02: hard resetting port ata5.02: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata5.03: hard resetting port ata5.03: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata5.04: hard resetting port ata5.04: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata5.00: configured for UDMA/100 ata5.01: configured for UDMA/100 ata5.02: configured for UDMA/100 ata5.03: configured for UDMA/100 ata5.04: configured for UDMA/100 ata5: EH complete I suspect that the root-cause of the problem could be drive-related. All the disks on the other Sil3726 are WD4000KD's and the disks attached to this one is 3xWD4000KD and 1xWD4000KS and 1xSamsung HD501LJ. Is there a way of test this? Is there an updated patch-set for port multipliers in a later kernel than 2.6.18.1? Regards, /LM
