Comment 1 arnaud.bawol 2016-01-21 09:33:25 UTC
Note : i'm on 4.3.3-301.fc23.x86_64 kernel

Comment 2 Jens Petersen 2016-07-26 02:22:29 UTC
Erm, sorry for late comment...

Where does your driver come from?

I think you've come to the wrong place/component.

Comment 3 Jens Petersen 2016-07-26 02:23:55 UTC
(wl is an old deprecated Emacs package - wanderlust MUA)

Comment 4 arnaud.bawol 2016-07-26 08:43:46 UTC
wl was the name of the kernel module that I was trying to modprobe.
Turns out that kern 4.4 fixed all my problems.

Comment 5 Jens Petersen 2016-07-28 05:46:13 UTC
Okay cool.
