https://bugzilla.kernel.org/show_bug.cgi?id=200045 --- Comment #2 from Wolfram Sang (wsa@xxxxxxxxxxxxx) --- Okay, these are actually two bug reports meanwhile: 1) 3e5f06bed72fe72166a6778f630241a893f67799 causes a regression when bit-banging I2C in software and results in keeping the screen black. 2) There is some regression when using the a HW interface for I2C which causes a reboot when changing the brightness. I'd suggest to work only on 1) here and create a new bug report for 2). I should be able to give you some patches to test in a few minutes. Thanks for the report and the bisecting! -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
