I've never built kernel stuff, so I was kind of afraid of taking this path. But, if there's no other way, perhaps the time has come for me to learn these things. > You may find that things work better with 2.6.15-rc3. So you think that this may be a 2.6.14 bug which is fixed in 2.6.15-rc3 ? My sincere thanks, Alan, for taking the time to analyze this. I had posted it in a couple of lists but nobody took a chance on it. I filed a bug on Debian package 2.6.14-2-686 but I'm not quite sure if it really is a bug.
