Hallo, * Eduard Bloch [Fri, Mar 25 2016, 10:12:24PM]: > I could try loading all regular modules one by one and look where it > starts breakin - would it help? Little update: loading known modules manually one by one did not break it. Finally I used a custom-build kernel with system specific config and that one works just fine. Kernel log is not helpful, in case of failure none is stored. Best regards, Eduard.
