Created attachment 836851 [details] syslog messages regardind the failed disconnect attempt Description of problem: When I disconnect my DVB-T USB stick, I sometimes get a kernel oops and the DVB subsystem is unusable, so that I have to reboot, which makes automatic recording unstable. Version-Release number of selected component (if applicable): Linux neo.intern.wgboome.org 3.11.10-200.fc19.i686 #1 SMP Mon Dec 2 20:48:22 UTC 2013 i686 i686 i386 GNU/Linux How reproducible: seldom (maybe 1% of all disconnects) Steps to Reproduce: 1. connect the stick 2. disconnect the stick Actual results: sometimes I get a kernel oops (see attachment). Expected results: it should just destroy the unneeded dvb structures... Additional info:
It's tainted as D in the backtrace you provided, which means the machine was already dying. Do you happen to have the first backtrace printed out?
the backtrace is the first Oops since the reboot at 2013-12-07... could the D come from the "BUG:" message some lines above? it is the first "BUG:" since the reboot at 2013-12-07... -arne
