S2API: problem unloading dvb_ttpci

I'm making my first steps in using the S2API driver, and already have a problem. When trying to do

/sbin/rmmod dvb_ttpci

I get the error

ERROR: Removing 'dvb_ttpci': Device or resource busy

'lsmod' shows

Module Size Used by
dvb_ttpci 348748 0

So who is using dvb_ttpci?

BTW: this worked fine with the 'multiproto' driver ;-)

After rebooting and doing one more test, I got this when running /sbin/rmmod dvb_ttpci:

Nov 22 13:21:35 vdr2 kernel: saa7146: unregister extension 'dvb'.
Nov 22 13:21:35 vdr2 kernel: PANIC: double fault, gdt at c2015000 [255 bytes]

Looks like the S2API driver isn't in a state where it can actually be used, yet...

Just for the record: it turned out that there was a mixup between DVB driver files from my SUSE 11.0 installation and the self-compiled driver source. After making sure only the self-compiled driver files were loaded, I was able to load/unload the S2API driver.

Sorry about the noise...
