just blacklist the evbug module and be done with

Carnophage · 2018/04/04, 21:12:15

That helps for evbug spam, but does not solve the lack of working touchpad/trackpoint or BUG: unable to handle kernel NULL pointer dereference at 0000000000000499

Got the evdev errors like a few others on IRC. My touchpad and trackpoint are working though.

hendrikL · 2018/04/04, 21:32:21

Thinkpad T410, touchpad and trackpoint working, kernel: 4.16.0-towo.1-siduction-amd64

Looks like it poped out in linux-media: https://www.mail-archive.com/linux-media@vger.kernel.org/msg128732.html

I have a feeling, that lack of touchpad/tracpoint is a side effect of the crash, as it breaks hw detection?

Carnophage · 2018/04/05, 13:37:01

FYI

Thanks for the heads up, i have added this patch and unset evbug in the recent kernel.

Carnophage · 2018/04/07, 11:28:35

I see that patch was reverted due to compilation issues. That's unfortunate but fully understandable.

I'm just wondering, what am I doing differently as I get a working deb by doing:
