This has been found by bisection and confirmed by reverting this commit on top of 2.6.33-rc1. Strangely enough, the box doesn't even have an AMD CPU, there's an Intel Core2 Duo in it, so I suspect some missing check somewhere. If I have the time, I'll look deeper into this tomorrow. [BTW, I can't recall seeing this patch before. That very well may be my fault, but please make sure that CCs of suspend-related patches are sent to me in future.] Rafael
