I compiled lynx gpio into kernel instead of compiling it as a module.
And the system got more stable - I rebooted my devices ~50 times
already and I do not see the boot problem I had before. 'CONFIG_..=y'
definitely makes the situation better.

As of bisecting - it will require time do find the commit. I might do
it if I find some spare time.
