I am a debian user and opened this bug report:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1050352

In the last mail I was pointed here.

So I now offer my help because I have the hardware and can reproduce the bug.

I am not a kernel developer. But I am able to modify kernel source files and
compile a custom kernel and let it run on debian, either debian stable or
debian testing.

May be I could test new versions of the driver.
