Hi, I upgrade a machine from 2.6.20->2.6.21-rc4 and am now having problems with my ATAPI device getting detected properly. Back tracking to 2.6.21-rc1, I find the problem existed there too, but not in 2.6.20. ahci 0000:00:1f.2: version 2.0 ACPI: PCI Interrupt 0000:00:1f.2[C] -> GSI 19 (level, low) -> IRQ 19 PCI: Setting latency timer of device 0000:00:1f.2 to 64 ahci 0000:00:1f.2: AHCI 0001.0100 32 slots 3 ports 3 Gbps 0x7 impl SATA mode ahci 0000:00:1f.2: flags: 64bit ncq pm led clo pio slum part ata1: SATA max UDMA/133 cmd 0xffffc20000028100 ctl 0x0000000000000000 bmdma 0x0000000000000000 irq 4346 ata2: SATA max UDMA/133 cmd 0xffffc20000028180 ctl 0x0000000000000000 bmdma 0x0000000000000000 irq 4346 ata3: SATA max UDMA/133 cmd 0xffffc20000028200 ctl 0x0000000000000000 bmdma 0x0000000000000000 irq 4346 scsi0 : ahci ata1: SATA link down (SStatus 0 SControl 300) scsi1 : ahci ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata2.00: ATA-7: HTS721080G9SA00, MC4OC10H, max UDMA/100 ata2.00: 156301488 sectors, multi 16: LBA48 NCQ (depth 31/32) ata2.00: configured for UDMA/100 scsi2 : ahci ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata3.00: ATAPI, max UDMA/100 ata3.00: qc timeout (cmd 0xa1) ata3.00: failed to IDENTIFY (I/O error, err_mask=0x104) ata3.00: revalidation failed (errno=-5) ata3.00: limiting speed to UDMA/66 ata3: failed to recover some devices, retrying in 5 secs ata3: port is slow to respond, please be patient (Status 0x80) ata3: port failed to respond (30 secs, Status 0x80) ata3: COMRESET failed (device not ready) ata3: hardreset failed, retrying in 5 secs ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata3.00: qc timeout (cmd 0xa1) ata3.00: failed to IDENTIFY (I/O error, err_mask=0x104) ata3.00: revalidation failed (errno=-5) ata3.00: limiting speed to PIO0 ata3: failed to recover some devices, retrying in 5 secs ata3: port is slow to respond, please be patient (Status 0x80) ata3: port failed to respond (30 secs, Status 0x80) ata3: COMRESET failed (device not ready) ata3: hardreset failed, retrying in 5 secs ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata3.00: qc timeout (cmd 0xa1) ata3.00: failed to IDENTIFY (I/O error, err_mask=0x104) ata3.00: revalidation failed (errno=-5) ata3.00: disabled - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
