I'm about as certain as I can be that ssuch "module-mixing" did not cause the hang that I saw on my laptop today, as I was able to successfully boot from a kernel built (along with world, at the time) on 19 May (after the gcc 4 import). In my case, the keyboard was unresponsive (e.g., didn't go into "scroll lock" mode when I used the keyboard chord to request that), and the fan started gaining speed pretty rapidly, so I elected to power-cycle the machine aftter a few seconds of trying less disruptive means of getting its attention. I believe the last message displayed had the word "probe" in it. I am certain that the system hadn't tried to mount any file systems yet. Sorry I don't have more specifics handy. I did save the hanging kernel, of course. Peace, david --=20 David H. Wolfskill david@catwhisker.org Anything and everything is a (potential) cat toy.
