this happens here repeatably (not always) if I switch to a TV
channel with DD and vdr starts a transfer thread for handling
that audio stream.

My /proc/interrupts was always clean. vdr was running under gdb
but I did never interrupt it.

please tell me what I should check. Would it make sense to add
debug output whenever vdr calls signal()? Are there other signal
sources I should watch?
