You are right it was serial port problem. I had wrong MAJOR and MINOR numbers in serial/pxa.c Now kerel boots and works fine with -ck patch. My I ask you if you (compulab) have any plans of merging machine cm-x270 patches into mainline kernel.

I think you have conflict between PXA serial and 8250 drivers. Make sure you use only one of them.

You are right it was serial port problem. I had wrong MAJOR and MINOR numbers in serial/pxa.c Now kerel boots and works fine with -ck patch. My I ask you if you (compulab) have any plans of merging machine cm-x270 patches into mainline kernel.
