I could not find this error anymore on any of the encrypted channels 
I could test it with but this currently does not include ORF.
Do you have this problem only on ORF or also still on other channels?

Well, a ksymoops dump would tell me a lot more than "it segfaults".
Which ioctl() calls cause the segfault?

I also don't understand how a channel being encrypted could make a 
difference inside an ioctl().
Outside of the firmware there is no longer any difference between
encrypted an unencrypted channels.
If the firmware would make problems or crash in this case I could 
at least understand it.
