Hello Stefan,

apologies for the delay in replying, I just got back from training in London.

I will attempt to answer your questions, see below

welcome to the list, the more people interested and willing to help
make more of this device, the better!

it's worth monitoring the Asus Transformer T100 group for when these
patches are updated, and some probably don't matter to us, but the
main thing is that they have quite a few people actively testing.

I've heavily tweaked my kernel config to try and omit anything I don't
think matters. I mainly work with a 32 bit kernel, so generally the
configs I publish are for that and I use "make menuconfig" to flip
them to 64 bit. John Brodie warns that reconverting back and forth can
result in things breaking.

those patches seem to mainly be for the Baytrail SoC to make the
driver work. I thought John Brodie had been incorporating those
patches... but nothing is constant here!

I think that's for the original Atom, whereas the modern baytrail
atoms are much more advanced.
My kernels are set to build for CPU architecture "core2/newer Xeon" ,
I've not noticed any problems.

great! I won't try this just yet as but maybe at the weekend.

reports on the T100 group suggest 4.6.1 is better than 4.6.0 and maybe
even 4.6.2. problem is that the hard lock-ups are hard to diagnose :-(

thanks for sending this to the group, I hope we can make progress
towards having a linux kernel which supports the Click Mini well.
