SubjectRe: Scheduling in interrupt BUG. [Patch]
Hi,

This patch solved the problem. Should be ready for inclusion in 2.4.
No more 'Scheduling in interrupt' under those conditions.
Thanx for the thoughts, solution and the amazing speed.
You guys are doing a really great job!

I hope we can get the earlier mentioned NULL ptr in all_ppp_units list
straight
soon. (I have a simple workaround - the mentioned hash, that even improves
speed,
but I a real fix would be more satisfaction. The relevant part of
ppp_generic.c
is so simple that it's really strange it is not correct.. ).

thanx:
Cell
