sascha confirmed on IRC that the above refers to XO-1.5 (and is good news on that front, of course). but bernie's referring to XO-1 behavior. i've been looking at the XO-1 issues recently, and my progress has been investigative, without a lot of actual discovery. :-) i think there are several issues, at least a couple of which have to do with races between suspend/resume and other driver activity.
