Is this desire for a single kernel just an abstract "it would be nice", or is
it a concrete practical "I tried to do something and the lack of unity made
it harder so I didn't bother"?
Because if you genuinely actively want to do something and find that the
situation with kernels makes that difficult, then I would like to help -
please be specific and I'll see what I can do.
But if this is an "abstract, would be nice", then I'll agree that it would be
nice, but keep doing what I'm doing :-)
Part of my thinking behind this is that fact that the current kernel in any
of its different forms is, from my perspective, effectively unusable. So it
doesn't really matter if there is one unusable kernel or several.
The main issue is power usage. This has never been brilliant but since the
switch to devicetree it has been much worse - a few hours standby time.
If/when I get that figured out I would be much more interested in providing a
kernel that provides all known features.
A secondary issue that has just arisen is that wifi appears to be completely
broken in 3.19-rc. I assume it was the removal of wireless-extensions (long
deprecated) but for some reason the libertas wifi driver doesn't associate
properly any more. I haven't had time to look at it properly yet.
If you are a user: I recommend either the 3.7 kernel (which I still use) or
the 3.12 kernel (which I haven't used, but I hear others have success with).
If you are a developer: I recommend starting with mainline and either working
on that, or looking and what others (myself and Nikalaus) have done to learn
from that and move on.
