X-Box one controller causes Xpad to crash [NEW INFO]

Still haven't got it on the mailing list... Also can't find any info on how to add new stuff. I already had sent an email sometime ago but since then I found out more.

[1.] One line summary of the problem:
X-Box one controller causes Xpad to crash

[2.] Full description of the problem/report:
Plugging in the so called "Xbox one (converted forces)" controller crashes the Xpad module.
Important part of dmesg:
"BUG: unable to handle kernel NULL pointer dereference at 000000000000004e" "RIP [<ffffffffc02c952a>] xpad_probe+0x37a/0x9eb [xpad]"

Hmm, not sure why your email do not reach the list, it does not require subscription for posting...

You need the following commit from mainline:

39a7a88872df98f0c3c50fe278fd1a1f597afd95 - Input: xpad - add Covert Forces edition of the Xbox One controller

There was a report that while it fixes the crash the controller is not really working, so I'd like to hear about your results.

Thanks.

Thanks for answering.

But shouldn't the commit be included in the "Linux version 4.3.0-040300-generic (kernel@gomeisa) (gcc version 5.2.1 20151010 (Ubuntu 5.2.1-22ubuntu2) ) #201511020949 SMP Mon Nov 2 14:50:44 UTC 2015" I tested with?

No, it was in the pull request I sent for 4.4-rc1.

Quoted 1 line

If not should I build the latest mainline kernel?

That would be great.

Thanks.

So I now was able to boot the new kernel fully (also onto desktop).

The patch fixes the crash and also the module gets successfully loaded dynamically.

But as you said earlier it isn't "working". jscal/jstest tell me the right amount of axes and buttons. But it doesn't matter if I calibrate the controller or not. Everything stays the same. I can move everything as much as I want but nothing changes in jstest.

Thanks for looking into this.
