I can confirm it with 2.6.0-test8 and simple modem connection (no pppoe). Connection is established, I get IP, DNS - everything but no IP packet ever seems to either go out or come in. The same works just fine with 2.6.0-test5; I have not tried intermediate versions. Probably if test9 is going to have the same problem I will have to. This happens every time on boot of test8 and works every time under test5
the system is Mandrake 9.2 without updates, compiler gcc-3.3.1 as shipped with mdk 9.2. previous kernel was compiled under mdk 9.1 with whatever compiler it had.
Enabling pppd debugging does not show anything interesting except it gets LCP echo from remote so some data _is_ flowing between systems. Enabling iptables LOG for all packets shows that packets _are_ submitted to ppp0.
So it looks like for whatever resons ppp0 either does not receive packet passed to it or never processes them.
As my knowledge of networking layer is near to zero, I appreciate pointers to where I can enable debugging, printk or whatever.
TIA
