I just got a new chipset (Gigabyte EP45-DQ6) courtesy of a competition. This coincided with the death of a hard drive. I had to reinstall my Gentoo system on the new hard drive, and hit this issue when booting the newly configured Kernel (2.6.29-gentoo-r5): ata1: link is slow to respond, please be patient (ready=0) ata1: softreset failed (device not ready) ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata1: link online but device misclassified, retrying ata1: link is slow to respond, please be patient (ready=0) ata1: softreset failed (device not ready) ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata1: link online but device misclassified, retrying ata1: link is slow to respond, please be patient (ready=0) ata1: softreset failed (device not ready) ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata1: link online but device misclassified, retrying ata1: limiting SATA link speed to 1.5 Gbps ata1: softreset failed (device not ready) ata1: SATA link up to 1.5 Gbps (SStatus 113 SControl 310) ata1: link online but device misclassified, device detection might fail ata2: link is slow to respond, please be patient (ready=0) ata2: softreset failed (device not ready) ... (as with ata1) This whole process takes a very long time (minutes) to finish. It seems to be down-grading two of the four SATA-2 drives to SATA-1 speeds. The drives are actually SATA-2 drives, and appear to work (at full speed) on my Windows 7 install. Please advise. Best, Marc
