I am totally new to BSD. Actually this bug is effecting me on Linux since 8 month, so I thought I give BSD a chance.
So I downloaded the BSD UEFI image and booted the system. When I can choose to install the system or use it as a live system, I can not use the keyboard to select anything.
It seems the OS does not recognize the Keyboard that is attached to SPI.
The Linux bug can be found here: https://bugzilla.kernel.org/show_bug.cgi?id=108331
Since I can not access the system right now and I am new to BSD, I can not give you any log files. If you show me how to to this, I go and get an external keyboard and give it a try ...
I'm working on this. The first step is attaching to Intel's SPI controller: https://reviews.freebsd.org/D29249 I am seeing the data packets with the spi(8) utility, so an input driver is not far away :)
