Problem with bttv in 2.4.3-pre[567]

[Stefan Becker]

Hi!

2.4.3pre5 must have changed something so that the bttv driver doesn't work
here anymore. Pre6 and pre7 the same, pre4 works.

I've diff'ed 2.4.3pre4/drivers/media/video and
2.4.3pre5/drivers/media/video but there were no changes. 

Excerpt from the syslog (I've set unsigned int bttv_debug = 1; in
bttv-driver.c)

unknown kernel: bttv0: open called
unknown kernel: bttv0: resetting chip
unknown kernel: bttv0: irq loop=0 risc=0, bits: HSYNC OFLOW HLOCK* VPRES*   HLOC => yes   PRES => yes

After that, the contents of the xawtv window freezes.
