Hi

I am using 2.6.8.1 kernel (mandrake patched).
I tested the refactored drivers with the TT DVB-C 2.1 Premium.
Drivers build ok and I was also able to load them succesfully.
(I build and loaded drivers separately from the build-2.6 directory.)

But when I started tuning channels with dvbscan (took head version of
dvb-apps from the cvs)
new drivers were pretty bad for finding channels.
I tested multible times and depending from the attempt results varied
from 0 found channel to maximum in 35 channels.

Could you try adding the line
mdelay(50);

to the end of ves1820_set_parameters() in the refactored drivers and let me
know if it helps?

Forget that - just try the latest FE_REFACTORING CVS and let me know how it goes.

Thanks for testing + reporting the problem BTW!

No problem, I just wish I could also be able to help in coding...
Anyway, it took me a couple of days to test because I was away for the weekend.
Tuning in FE_REFACTORING branch has now improved a little but it is still not as good as compared to the
drivers in the HEAD. Now 44-59 channels were found. (Head founds always 77)

Is there any simple timeout parameter I could try to change from the drivers for testing?
Log from the last attempt is below.
