Subject: Re: [linux-dvb] dvbnet not working anymore with 2.6.25

Message-ID: <g1f8kg$upn$1@ger.gmane.org> (raw)

I've narrowed down the problem to kernel version 2.6.24.
This is the output with
# strace ifconfig dvb0_0 10.0.0.1 promisc up

Not being a kernel hacker I was not able to investigate deeply the problem.
Can it be related to new NAPI in /net/core/dev.c? I don't have a clue.
Also no answers on this ml, so probably I'm alone with this problem.

thanks,
Francesco
