[linux-dvb] Problems with Twinhan on 2.6.3 kernel

[Mike Frisch <mfrisch@isurfer.ca>]

After just learning that my Twinhan VP-1020 (original) card might now be
supported under Linux, I attempted to get it running on Fedora Core
2-test1 with kernel 2.6.3-1.97.

As per the documentation, I loaded the modules with:

$ modprobe bttv i2c_hw=1 card=0x71
$ modprobe dvb-bt8xx
$ modprobe dst
			
which yields the following in the 'dmesg' output:

Linux video capture interface: v1.00
bttv: driver version 0.9.12 loaded
bttv: using 8 buffers with 2080k (520 pages) each for capture
bttv: Bt8xx card found (0).
bttv0: Bt878 (rev 17) at 0000:02:07.0, irq: 10, latency: 32, mmio: 0xe2001000

DVB: registering new adapter (DST).

bt878 find by dvb adap: checking "DST"
dst_check_ci: recognize DST-020
DST type : satellite
DST type flags : 0x4 symdiv
DVB: registering frontend 0:0 (DST SAT)...

All seems well until I attempt to tune a signal (any signal) with
'dvbtune', I get the following:

Badness in interruptible_sleep_on_timeout at kernel/sched.c:1938
Call Trace:
 [<c0120ed2>] interruptible_sleep_on_timeout+0x5d/0x23a

 [<e0c217f6>] dvb_frontend_thread+0x0/0x238 [dvb_core]
 [<c01091d5>] kernel_thread_helper+0x5/0xb
		 
I have yet to try the latest version of the linuxtv dvb driver, as I
initially had some problems compiling it (haven't investigated those
yet).

Any comments?

Thanks,

Mike.
