As far as I recall this has bee
I think I've found the problem:
static int cinergyt2_fe_set_frontend(struct dvb_frontend *fe,
struct dvb_frontend_parameters *fep)
{
struct cinergyt2_fe_state *state = fe->demodulato

Anyone listening?

To unsubscribe from this list:
I've added dummy 32-bit variables to dvb_frontend_swzigzag_autotune() to change
the
frame size. Here are the results for mythweb (can tune/cannot tune):
#variables i486 i586
0 ok failure
1 failureok
2 ok ok
3 failu
I've now compared the generated assembly code for
dvb_frontend_swzigzag_autotune()
built with CONFIG_M486 vs. CONFIG_M586. Both versions are correct, but the one
compiled
with -march=i586 (for which tuning does not work) uses more stack space (one
32-bit
word).
Does this ring any bells?

The more I look into this problem the stranger it becomes. I've compiled
the kernel for different CPUs:
|mplayer mythtv
-+
CONFIG_M486 |works works
CONFIG_M586 |works
There are two new discoveries about my Cinergy T2 problem:
- the Cinergy T2 works when attached to an Intel Core2 board, but doesn't work
when
attached to an Intel Atom N270 board (tuning times out)
- "git bisect" of the Linux kernel points to a bad merge of
commit 60db56422043aaa455ac7f858
My Cinergy T2 (T²) doesn't work with kernels 2.6.30, 2.6.30.1, and 2.6.31-rc3,
but it works with kernel 2.6.29. The kernel logs
dvb-usb: recv bulk message failed: -110
and the application (I've tried mythtv and mplayer) trying to access the DVB
receiver
times out when trying to tune to a cha
