Subject: boot failure with 4.13.0-rc6 due to ATA errors

Not sure why mailing list to direct this bug report to, so starting with
libata based on the error messages.

Some where between v4.12 and 4.13.0-rc6 a Celestica redstone switch
fails to boot due to ATA errors:

[    9.185203] ata1.00: failed to set xfermode (err_mask=0x40)
[    9.500825] ata1.00: revalidation failed (errno=-5)
[   20.449205] ata1.00: failed to set xfermode (err_mask=0x40)

I just tried Linus' top of tree (cc4a41fe5541) and it still fails. With
v4.12 the same switch boots and 'dmesg | grep ata' shows:

Given the overhead of building, installing, booting and recovering from
a failed boot, 'git bisect' is not a realistic option for this switch
option unless some one can cut the span to a few iterations.

If it helps, lspci and lsscsi output from an older kernel:
