Problem is in that the in last 5-6 months chrome-os kernels even don't boot, i.e. I only get blank display. I patched it for few releases locally but for about 3-4 months even my patch doesn't work. Maybe I could find chrome-os kernel about year or two old and try, but even then I don't know where to look for this problem. Other option is to try with mainline kernels from 4.20.x and up one by one major release to look on which version this problem started. This will take time because problem occurs irregularly, sometimes in a few hours but sometimes it works fine for a few days until it appears. Thank you for pointing me whom to ask and what to try. -- Kind regards > Kind regards > Uff > > > > > On Sat, 2020-03-21 at 21:46, Milan P.
