dvb_usb_pctv452e driver problems

I am looking problems with that driver. It is said to be buggy after merged to mainline Kernel.

It supports three different devices:
PCTV HDTV USB
Technotrend TT Connect S2-3600
Technotrend TT Connect S2-3650-CI

All reports are welcome even when it is working as expected.

In problem case I would like to ask if you could test that tree and report if it helps:
