Hi John, We applied this patch on a test CPE and LNS against 2.6.32 and the issues appear to be resolved! We're still conducting more extensive testing, but so far it's looking good.

We did some testing with a self-made patch experimenting with ppp_mp_explode: http://lkml.org/lkml/2010/3/26/170 I should mention that we are working with 2.6.31 systems and the patch should be applied against the corresponding sources. Are your problems related to 2.6.32 specifically? We are not that familiar with ppp- or kernel development, so this can't be considered a final solution for the problem, but our results with this workaround look promising. It would be great if any of the more experienced developers on this list could have a look at this problem and solve it the "right" way.
