Re: [PATCH] dell-laptop: rfkill blacklist Dell XPS 13z, 15z

[Jean-Louis Dupond]

Hi

I'm the owner of a XPS 15, which has this issue.
The best solution would indeed be to solve the real bug, and not work
around it in Linux.

But still, if we can fix it with rather small impact/code on linux, I
think we should just do it.
It makes linux more user friendly this way.

A small remark also:
Is it really possible to disable bluetooth without killing wifi in
Windows on the XPS?
Not that I use windows alot, but it doesn't seem to work perfectly in
windows neither.
This bug is prolly not very common, as default XPS doesn't have a
bluetooth chip.


Thanks
Jean-Louis
