--- Comment #15 from Jan Viktorin <iviktorin at fit.vutbr.cz> ---
With 4.4.48-1-lts, I can see the following errors in dmesg:
[2214848.975943] [drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR*
uncleared pch fifo underrun on pch transcoder A
[2214848.975954] [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH
transcoder A FIFO underrun
[2214848.980066] [drm:intel_set_cpu_fifo_underrun_reporting [i915]] *ERROR*
uncleared fifo underrun on pipe B
[2214848.980077] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU
pipe B FIFO underrun
The screen DOES NOT freeze anymore. At least, I did not notice it for some time
now.
What is very strange, Chromium does not redraw. I can click on buttons and they
seem work (e.g. close tab quits the application), however, the browser does not
show any changes.
Please, can you specify the term "latest kernel" next time? Do you mean a
certain latest release or the current master? I do not build my own kernels...
