Re: Fedora 30 drm error

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.
