[linux-dvb] System freeze loading dvb-bt8xx.ko under 2.6.5 with Avermedia dvb-t

["Tom Parker" <tparker@netspace.net.au>]

Folks,

I'm having trouble getting an Avermedia DVB-T working under 2.6.5 using
bttv-0.9.15 & dvb-kernel cvs latest as of yesterday.  The system freezes
when I load dvb-bt8xx.o.  I've just bought this card so this is a new
setup.

Part of the problem is possibly the unrecognised card stuff reported by
bttv.

I've tried card=6 with the same freeze, none of the other card= options
look likely.  Can someone enlighten me here?  From
http://www.linuxtv.org/mailinglists/linux-dvb/2003/09-2003/msg00115.html
it looks like the Avermedia should be card=105 with 0.9.11, but in
0.9.15 card=105 gives "Apr 22 19:56:47 guatemala kernel: bttv0: using:
ProVideo PV143 [card=105,insmod option]"

Loading the bt878.ko module gives.

Apr 22 19:46:06 guatemala kernel: bt878: AUDIO driver version 0.0.0

Loading dvb-bt8xx.o freezes.

I'm using the kernel parameter noapic to avoid problems with acpi
support for the VIA chipset.
