No where practical to capture them to. I don't know if the machine was entirely dead, or just the console at that point. > Also, as you seem to be able to easily reproduce the bug, git-bisect might > reveal the culprit easily.

But if there were some likely candidates, I could probably try a couple. Mostly I just wanted to give a heads-up that all is not well with 2.6.25 for now, and I'll get round to debugging it when I have time to do so.
