Hello, all. Torsten, Clarence is reporting similar problem on 2.6.22. The original message follows. > I'm using the 2.6.22 sources with a Sii3132 SATA controller and a Seagate HDD. > What I've noticed is that it often fails to boot with this configuration. > Warm boots appear to always fail while cold boots (power-cycles) fail maybe > 20%-50% of the time. Here's a log from my last attempt: > > Loading iSCSI transport class v2.0-724. > PCI: Enabling device 0000:01:00.0 (0000 -> 0003) > scsi0 : sata_sil24 > scsi1 : sata_sil24 > ata1: SATA max UDMA/100 cmd 0xe1258000 ctl 0x00000000 bmdma 0x00000000 irq 0 > ata2: SATA max UDMA/100 cmd 0xe125a000 ctl 0x00000000 bmdma 0x00000000 irq 0 > ata1: SATA link down (SStatus 0 SControl 0) > ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 0) > ata2.00: qc timeout (cmd 0xec) > ata2.00: failed to IDENTIFY (I/O error, err_mask=0x4) > ata2: failed to recover some devices, retrying in 5 secs > ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 0) > ata2.00: qc timeout (cmd 0xec) > ata2.00: failed to IDENTIFY (I/O error, err_mask=0x4) > ata2: limiting SATA link speed to 1.5 Gbps > ata2.00: limiting speed to UDMA7:PIO5 > ata2: failed to recover some devices, retrying in 5 secs > ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 10) > ata2.00: qc timeout (cmd 0xec) > ata2.00: failed to IDENTIFY (I/O error, err_mask=0x4) > ata2: failed to recover some devices, retrying in 5 secs > ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 10) > ata2: EH pending after completion, repeating EH (cnt=4) > i2c /dev entries driver > IBM IIC driver v2.1 > > If the boot succeeds, I have no further problems with HDD access. > I also did not see this problem with the 2.6.17 kernel.

Can you update us on how the testing of patched kernel went? -- tejun - 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
