Yes sure. In my very specific case, I noticed this bug because at boot time the desktop refuse to run. In fact, I have installed GDM and I am opening the X server directly on my account in graphical mode (I know it's bad). So, at boot time the sequence should be: X server --> GDM --> Desktop (Gnome2) But, this bug (when it occurs) seems to stop the process always at the exact same point which is when starting the Desktop (gnome-panel and so on). At this point, the mouse pointer is still active and the X server as well (I can only move the mouse, not really useful indeed). If I stop the X server and try to restart, I can't. I get the exact same error than for the gnome-panel but for the X server (I guess, I have to investigate this a little bit more now that I better know what is going on). My point is that it seems to be extremely consistant when it occurs. So, I think that there is some determinism inside this bug since it started. The theory of the "wrong code" being remanent in the processor does not really satisfy me because we have no real evidence of it (how could we dump the registers of the processor or the cache memory ?). The problem is that I do not exactly understand everything and I have to investigate a lot before reporting. I'll try to do some investigations and I'll probably come back with a summary of my though. I guess that I have to add this to the follow-up to the bug #216933 as it was the first. It seems to be a very interesting bug. And, actually it crash my X about one time out of three boots, so I would be very happy to get rid of it.
