Hi,
After the upgrade from 2.5.73-bk1 to bk2 the pppd daemon is killed, so the ppp connection is impossible.
After the reverse of the patch I can connect.
I also applied the bk2-bk3 patch (without the bk2), and I have no problems.
So the problem is in bk2.

I can confirm it.

What is your ppp configuration, anything special? Is serial line fat or slow? Is this on SMP or UP system?

I can't reproduce this over a null modem cable so trying to see what could be different.

It's a external serial (ttyS1) 56k modem (Supraexpress 56e). It's a SMP system.

I reverted your changeset and everything works again. pppd version is 2.4.1 (debian sid environment) Config is attached.

This is the dmesg output when it works:

I've got this exact same problem on 2.5.73-bk5. Connection gets dropped just after a connection. When I switch back to a previous kernel everything works fine. Setup is

PAP authentication
56K v.92 modem connection over USB serial connection UP kernel on P4 1.8 GHz

Let me know if there's anything else I can check.

The only way I found is to take the drivers/net/ppp_generic.c from the original 2.5.73.
Neither the patch sent me by Diego Calleja García works :/
