Haswell (HSW) This is verified by _multiple people_ using different methods. All his is documented in [1] , Kernel 5.6.19 was fine Result: no output, no usable desktop due to gpu crashes Hardware : 2x Acer C720 Chromebooks and potentially others Methods: - running mpv with vaapi enabled - glxgears - automatic desktop environment start (probably with acceleration) There is atm no fix in drm-tip integrated (5.9.0_rc5bisect_g30b3e38bd6d5 for example still errors) and no activity from Intel in the bug report beside the "working" suggested patches / hacks there There should be enough bisection info an there. Nobody asked there to get more info or different bisects/trees. So - the ticket is still open. Because Fedora uses newish Kernels I would like to use it "normally" without going for 5.4 LTS or waiting an unknown amount of time - as 5.9.x currently seems to have the same regression. Affected Hardware at my end: - C720 with a Intel Celeron 2955U - UEFI Bios instead of original Bios (mrchromebox.tech) if thats relevant for hardware init related bugs; But the Kernel should take care of the correct initialization anyway Feel free to comment which trees, branches, tags or patches we should try to help and what _more_ to report for "Report-By" , "Tested-By", "Verified-By" tagging so that [1] can be closed.
