Sorry, the drivers for kernel 2.4 are old and unmaintained.

If you are using the 1.1.1 driver tarball you might update your driver
from http://linuxtv.org/cgi-bin/viewcvs.cgi/dvb-kernel/

Rev 1.62 of dvb_net.c contains a fix which might solve your problem:
'Fix locking to prevent Oops on SMP systems when starting/stopping
dvb network interfaces.'
