Hi all,
When porting ivtv to 2.6.20 I discovered that I got errors when loading
the cx25840 module and that that module couldn't load the firmware
anymore.
I've just discovered that changes in 2.6.20 brought a cx25840 bug to the
surface (it was always there). I've made a patch and pending some
testing it should end up in 2.6.20.1 (it's a pretty serious bug after
all), but this means that cards with a cx2584x won't work with 2.6.20
unless you manually apply the attached patch.
If you have a saa7115-based card (pvr250/350), then it will work fine.
The ivtv trunk has been patched as well to support 2.6.20.
Next kernel cycle I really should do some tests before the kernel is
released :-(
Regards,
Hans
