https://bugs.freedesktop.org/show_bug.cgi?id=104064 --- Comment #35 from taijian@posteo.de --- Created attachment 138032 --> https://bugs.freedesktop.org/attachment.cgi?id=138032&action=edit dmesg output with the patch from comment #34 OK, I've recompiled the kernel with v2 of your patch (comment #34) and tested for three power cycles. The problem with the backlight seems to be gone, so presumably the patch did what you intended it to do? Also, so far the system seems stable, the dGPU powers up AND down nicely. -- You are receiving this mail because: You are the assignee for the bug.
