That's interesting. The link state seems to oscillates for quite long
time. Can you please try the followings?
1. Change sata_deb_timing_hotplug to sata_deb_timing_long in
ata_piix.c::piidx_sidpr_hardreset() and see whether it solves the
problem?
2. Switch the controller into ahci mode in BIOS if possible and see
whether the problem goes away.
3. Try kernel parameter "libata.force=nohrst" and see whether it makes
any difference.
Thanks.
