Thanks for the info Theodore, this is definitely looks like some type of
regression in 2.6.29, as the problem is not evident when I s2disk using
2.6.28.9, even after multiple suspend/resume cycles.

I found some 'ATA bus errors' and 'SError' messages in
/var/log/messages, so I've attached the messages from both 2.6.29 and
2.6.28 for comparison.

Regards,
Niel
