That's possible - although as of late i'm generally finding new regressions, the old once-in-a-blue-moon races i've triggered already. (the roughly half a million random bootups i've done in the last 2 years in -tip testing went a long way in rooting them out) I'll try to figure this one out in a few days hopefully - the laptop is not available for testing right now for other reasons.
