Hi, whoever reads this...
I just did some tests with the debian kernel and the 2.2rc13 suspend2:

STRANGENESS:

(1) The skystar2 driver is now renamed to "b2c2-flexcop-pci"  ?
(2) Driver unload does no longer crash the system, the frontends 
     get automatically unloaded. udev works fine (if you like it), the
     device nodes are automatically created and removed.

BUG:

(3) After suspend2/resume while playing a radio channel the driver says:
             kernel: b2c2-flexcop: i2c master_xfer failed 
     The radio did not continue to play. Very disapointing

A MORE SERIOUS BUG:

(4) The driver (?) does not clean buffers correctly. You will probably not
      notice this for TV channels, but it hurts for radio (lower data rate).
      After tuning to another channel fragments of old data get delivered
      and cause odd sounds. My software (zapdvb) closes all filehandles
      before tuning to another channel (in fact a new process is started).

QUESTION:

(5) Did tuning get slower or is my impression a result of (4) ?

Anyhow, the drivers in 2.6.14 seem to be a progress (as we can now start to 
play with suspend2 without crahing the system).

The Bug (4) does not apply for the budget driver (KNC1). Unfortunately I 
cannot test suspend2 with it (card installed in a server).

Yours
Jürgen
