From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050922 Fedora/1.0.7-1.1.fc4 Firefox/1.0.7 Description of problem: When running scandvb or tzap with the Freecom DVB-T USB stick the kernel oops. Sometimes the system stop responding and sometimes it does not. Version-Release number of selected component (if applicable): kernel-2.6.14-1.1644_FC4 dvb-apps-1.1.0-1.fc4, dvb-usb-wt220u-01.fw How reproducible: Always Steps to Reproduce: 1. Insert stick and wait for the device to settle Alternative 1 step 2. launch scandvb to scan for channels Alternative 2 step 2. launch tzap to tune the stick Actual Results: Step 1. Works with the following complaint "kernel: dvb-usb: recv bulk message failed: -110" Alternative 1 Step 2 Will cause the system to lock up completely without any explaining log entries resolved only by power cycling the system. Earlier scandvb testing produced output found in attachment 1 [details] Alternative 2 Step 2 Will result in messages in /var/log/messages attached as attachment 2 [details] Expected Results: I'd expect the system to keep running. Additional info: This is the command I use to produce the error root@pcp103814pcs jrv]# tzap -c channels.conf TV4 using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' tuning to 754000000 Hz video pid 0x0419, audio pid 0x0418 (this command is hanging since)
Hmmm... the links to the attachments are somehow created by the system itself and they are WRONG. They have nothing to do with my report.
Created attachment 121582 [details] Attachment 1 [details] /var/log/messages from several tests with kernel 2.6.14-1.1637
