Hi, I tried something simple with three kernel versions: 2.6.30, 2.6.31, and 2.6.32.7. But I can't reproduce the problem that way. Just after booting I run alternatively /opt/dvb-apps/bin/szap -a 0 -r "CCTV 4" /opt/dvb-apps/bin/azap -a 1 -r "57.1" and then I run them concurrently and finally I disconnect the USB tuner and replug and retry the 'azap' I did not get any crash yet. So there is likely some other "environmental" condition that is relevant. I will continue using 2.6.32.7. Whenever I meet the problem I will take note of the environment and try to reproduce the same environment with other versions of the kernel. Thanks
The only "major reorganization" in that time period I can think of is a couple of the files related to IR support were moved. Further, the problem appears to be in the implementation of request_firmware() and doesn't look specific to any changes in the v4l-dvb tree. All I can suggest at this point is you try to narrow down what release the breakage was introduced in, at which point we can take a look at what changed. Devin
