Macbook 12'' 2015: can't start keyboard

I've tried to start linux on Macbook 2015.

But keyboard doesn't work (kernel starts, etc, but local keyboard doesn't work)

/proc/bus/input/devices doesnt contain any keyboard records.

dmesg contains several xhci_hcd timeouts:

dmesg|egrep 'xhci|hub'

I've seen the patch
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=dbe08116b87cdc2217f11a78b5b70e29068b7efd
It is applied and compiled, but keyboard don't work yet.
Unfortunately I can't find ticket about keyboard and macbook 2015.
