Please note what I asked for: a case where udev worked with 2.6.x.y-n but not with 2.6.x.y . I've run Fedora with compiled versions of 2.6.m (up to 2.6.22 which I'm running now) and had no problem with udev. Of course you need an appropriate .config file. I've no doubt it is possible to choose options which confuse udev. >> I asked you for an example of this. >> You didn't given one, so I assume you cannot find one. > >> > Currently the kernels are distributed compiled for several cpu >> versions >> > so that is not something that needs to be done by the user. >> >> Not true. >> None of the distribution kernels I have seen >> use CPU choices that accurately match any of the machines I have. > What do you make of the fact that the 2.6.22.1-33.fc7 kernel came in two > rpms. One called 2.6.22.1-33.fc7.i586 and the other called Why don't you do what I suggest, and look at the .config files for these kernels? I just looked at kernel.i686 2.6.22.1-41.fc7 and the CPU choice was "Generic architecture". There are many other places where "generic" choices are (necessarily) made. If in fact this is just as good as making the choice reflecting one's actual hardware, it is difficult to see why one should be given a choice. This kernel, incidentally, is almost twice as large as my compiled kernel, while the /lib/modules/ directory is 8 times as large. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
