Hi Rodrigo, Thank you Rodrigo for the reply. After some time of debug, and finally with memtest86, I find there is memory corruption issue in this workstation, even kasan kernel can't detect, so finally I decide to use memtest86+ to do the detect. After I added a 'memmap=2G$4G' in cmdline, the issues was not shown yet. So sorry for the noise. I'll open bug if I hit the issue again. And thanks for the detailed link about how to report bugs and how to enable debug options. ----- Original Message ----- > From: "Rodrigo Vivi" <rodrigo.vivi@xxxxxxxxx> > To: "Chunyu Hu" <chuhu@xxxxxxxxxx> > Cc: "Joonas Lahtinen" <joonas.lahtinen@xxxxxxxxxxxxxxx>, "Jani Nikula" <jani.nikula@xxxxxxxxxxxxxxx>, > intel-gfx@xxxxxxxxxxxxxxxxxxxxx > Sent: Monday, July 8, 2019 10:33:01 PM > Subject: Re: Fedora 30 drm error > > 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.
