The drive is connected to the ICH9R southbridge of an Intel P35 chipset motherboard. I can boot from the CD/DVD so the drive itself is working, but the kernel reports the following: scsi4: ahci ata5: SATA link up at 1.5 Gbps (SStatus 113 SControl 300) ata5.00: ATAPI, max UDMA/66 ata5.00: qc timeout (cmd 0xef) ata5.00: failed to set xfermode (err_mask=0x104) ata5.00: limiting speed to UDMA/44 ata5: failed to recover some devices, retrying in 5 secs ata5: port is slow to respond, please be patient (Status 0x80) ata5: port failed to respond (30 secs, status 0x80) ata5: COMRESET failed (device not ready) ata5: hardreset failed, retrying in 5 secs ata5: SATA link up at 1.5 Gbps (SStatus 113 SControl 300) ata5.00: ATAPI, max UDMA/66 ata5.00: qc timeout (cmd 0xef) ata5.00: failed to set xfermode (err_mask=0x104) ata5.00: limiting speed to PIO0 ata5: failed to recover some devices, retrying in 5 secs ata5: port is slow to respond, please be patient (Status 0x80) ata5: port failed to respond (30 secs, status 0x80) ata5: COMRESET failed (device not ready) ata5: hardreset failed, retrying in 5 secs ata5.00: ATAPI, max UDMA/66 ata5.00: qc timeout (cmd 0xef) ata5.00: failed to set xfermode (err_mask=0x104) ata5.00: disabled This is 2.6.19 (probably with a few distribution patches) on an install CD. I also tried setting the SATA controller to a 'compatible IDE' mode and the hard drives and DVD drive are detected and work properly. Any ideas what to try to get it working under AHCI? -- Tom Lanyon
