Hi Chunyu, First of all sorry for the delay on the response here. Many of us were out on vacation and holidays. Also in general please use https://bugs.freedesktop.org/ to report bugs. Please make sure you read this before: https://01.org/linuxgraphics/documentation/how-report-bugs (more inline) On Tue, Jul 02, 2019 at 12:42:02AM -0400, Chunyu Hu wrote: > Hi Rodrigo, Joonas and Jani, > > I'm meeting some drm issues when using Fedora 30.

Best way to find out if we have had a fix for that is to try out drm-tip: https://cgit.freedesktop.org/drm-tip/ > > [43401.062181] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun Recently we had many patches touching watermarks and other related areas that usually are known for FIFO underruns. Another good reason to try drm-tip. And if that is fixed on drm-tip and you need to find the exact patch that fixed the issue you need to perform a reversed bisect. > > > What's worse, I met a gnome-shell broken when reading drm : It seems yet another issue to be reported at bugzilla.freedesktop.org And also to check reproduciablitity with drm-tip...
