[linux-dvb] Oops with kernel 2.4.13 and latest dvb-driver

[frank.private@t-online.de (Frank Klingenhoefer)]

Hi,
I am using kernel 2.4.13, the latest (CVS of today) dvb-driver and a
dvb-s card (version 1.3).

If I do the command "make insmod" in $DVB/driver or if I load the
modules in the following order

1 - modprobe tuner
2 - modprobe VES1893
3 - modprobe saa7146_v4l
4 - modprobe dvb

I can use (n)tuxzap + xawtv or vdr (v.0.96) + xawtv without major
problems.

If I load the modules in another order  

1 - modprobe dvb
2 - modprobe tuner
3 - modprobe VES1893
4 - modprobe saa7146_v4l

and try to tune a channel (using tuxzap or vdr) then the tuning app
dies.

I can see the error message in my log file:

[...]

Some more information:
  
debian:/home/frank# nm -n /usr/src/linux/vmlinux|grep c0111f
c0111f20 T free_dma
c0111f50 T add_wait_queue
c0111f50 t gcc2_compiled.
c0111f78 T add_wait_queue_exclusive
c0111f9c T remove_wait_queue
c0111fb0 t get_pid

I know how to get my box to work, but the above behavior is a failure
(in my opinion).

Any comments?
