i've checked and your original code, modified to compile and including
my changes to control the LNB works very well; the patch you posted
does not. i have swapped between the two and rebooted several times to
make sure.
i will do a diff and see what the differences are

the main changes seem to be a reworking of the interrupt handling and
some i2c changes

How fast is your system?
reasonably fast
it is a dual core AMD64 X2 running at 3.1GHz
Main change is to move demuxing from interrupt to work handler.
So I prepaired another patch, with separate work queue.
May be you find some time to test.
I wonder CPU usage and interrupts count(cat /proc/interrupts) while viewing DVB.
I guess your card generates a lot of unnecessary(unknown ?) irq's.
Another idea is to increase dma buffer.
i've tested that now
sorry for the delay - at a family wedding
anyway, that seems to work fine. will st some more, but the first
results (with kaffeine) seem good.
i did a complete scan and then tried about 20 different channels. they
all seemed to work fine.
thanks
