[linux-dvb] OOPS in 2.6 SMP

[Vincenzo Di Massa <hawk78_it@yahoo.it>]

Hi list,
I managed to connect to my sat provider using 2.4 and my SS2.
I'm trying to use dvbnet on 2.6: the problem is that it hangs my
keyboard (SysRq works, but how do I dump the output to a file?).

I can reproduce the problem just running dvbnet.
I tried :
1) szap ; sleep 5 ; dvbnet
2) dvbnet ; sleep 5 ; szap

Both work on 2.4 and break 2.6.

Today , somehow the keyboard worked enaught to dump dmesg.

Attached is the relevant part of it.
