2.6.28.7: ATA errors after hibernation

2.6.28.7: ATA errors after hibernation

[Niel Lambrechts]

One more obstacle in my perpetual quest to have an empty /var/log/warn! :)

The following messages get logged after resuming from s2disk on my W500
Thinkpad running 2.6.28.7-pae. I do not notice any tangible ill effects
though:

Could these be linked to cases of human sleep deprivation or is this
joyful and harmless hardware chatter?
