That might well be the culprit. I didn't check for changes in the dvb core, I should have done that. That patch was introduced in 6.3.7 and reverted in 6.3.9. That doesn't quite match the "#regzbot introduced: v6.3.5..v6.3.7" report, though. I wonder if fedora backported that problematic patch to their v6.3.5 release?
