Setting intel_idle.max_cstate=1 works as a crude workaround. Created attachment 278825 [details]

Thanks Matthew for the information. @Rui, @Len, we'll try to contact the graphic team for detail of the fix for windows. I actually had to use intel_idle.max_cstate=0 to stop the hangs completely. When the hang happens on Linux, the LED sometimes displays the CPU error beep code. (two ambers, one white) A better workaround is to use i915.enable_dc=0 I'll file a bug on freedesktop to loop i915 people for comment. Have an issue with Dell latitude 5590 like that: https://www.dell.com/community/Latitude/Latitude-5590-bios-gt-1-8-suspend-issue-ubuntu-led-error-pattern/td-p/7326963 i915.enable_dc=0 works for me, but now FAN is not stopping even CPU is not being hot. Is there any solutions of that issue? FYI i915 developers won't look at this bugzilla. Please file i915 issues at the freedesktop.org gitlab https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs |
