Thanks for not killing the driver :-) Feel free to add me to your list
of testers in case you need more testing in the future.

I already posted the problem [1] but didn't CC you since your name
wasn't listed in MAINTAINERS. I recompiled the kernel and tested again,
but the output doesn't seem to contain extra output.

In order to compile the kernel with IDETAPE_DEBUG_LOG enabled I had to
apply the following build fix.
