Andrew,

Sorry for the late reply :

I made the patch -R of ppp stuf against mm3-1 : same result as with the
patch.

I thought making a strace -f pppd of both a working kernel (test2-mm2)
and the first non working
(test2-mm3-1) can be usefull, strace result files are available at
http://coste.florent.free.fr

(pid of mm3 have been changed to match the ones of mm2 so that the diff
is easy to read).

I also made the same test with test2-mm4 : same result as mm3-1. I'll
test 2.6.0-test3(-mm1) soon

Great Regards,

Florent
