Running mainline kernel 4.0.3 (Arch Linux ARM) on a Cubietruck I
recently stumbled upon some systemd journal messages during boot that
seemed possibly related and hence worth posting to me:
> sunxi-mmc 1c12000.mmc: No vqmmc regulator found
> sunxi-mmc 1c12000.mmc: base:0xf011e000 irq:27

I don't know if it is your problem, but maybe it helps:

Module ap6210 is a modified version of module bcmdhd, which is part of
linux-sunxi and Android kernel, to address some problems on Cubietruck.
I had tried to address this some months ago which unfortunately didn't
yield any response
(https://groups.google.com/forum/#!topic/linux-sunxi/-GejF5r-HGg).
In addition to the findings described in that posting bandwidth seems to
matter as well. By limiting to about 200kB/s the problem was mit
boot a new kernel just fine with the slightly
less optimal pll5 div chosen when building with "Enable workarounds
for booting
old kernels"
So yes you can boot both kernels with a single u-boot binary.

That's exactly the kind of information I was hoping to

This indeed did the trick.
So thanks a lot for your quick and helpful reply.
There's one thing that bothers me, though: the PR you stat
27;s upstream source tree. Any ideas how to fix this?
Thanks in advance,

But that's all I could figure out.
So I was wondering whether there's any news about this problem or even a
workaround. Obviously I'd be willing to perform further tests but needed
some advice on how to do this.
