Hi,

Further to emails from November and December last year that Tejun Heo
was investigating:
http://markmail.org/message/l3g3s27rwj6iuhje#query:Intermittent%20SATA%20failures%20%22%28link%20offline%2C%20clearing%20class%201%20to%20NONE%29%22+page:1+mid:g6ujvdfz4om2rnvf+state:results

I'm having the exact same problem, see below excerpt from dmesg. Note
that the disk that fails is seemingly random:
ata2.00: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
ata1.00: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
ata2.01: SATA link up <unknown> (SStatus 300 SControl 123)
ata2.00: link offline, clearing class 1 to NONE
ata1.01: SATA link up 3.0 Gbps (SStatus 123 SControl 300)

I have attached a good and bad boot.

lspci -v shows:

I'm currently running linux-2.6.32-gentoo-r7 on amd64 but I've tried
linux-2.6.31-gentoo-r6 and linux-2.6.31-gentoo-r10 with the same
results. libata.force=nohrst makes no appreciable difference

As before 'echo "- - -" > /sys/class/scsi_host/hostX/scan' where X is
0 or 1 brings the drive back online.

As the original chat petered out I was hoping that this had since been
fixed. Anyone have any suggestions please?
