Please attach the output of dmesg after the problem occurred. Created attachment 126453 [details]
Boot log
Output of journalctl --boot=-1
Thanks Michel Output attached as requested. This log was generated after a full boot. As soon as you leave the GRUB menu the screen starts to look as if its mode switching, this lasts for about 5-10 seconds before it stops with a black screen with the backlight on. Many thanks James Any chance you can try a newer kernel? a convenient way to try newer kernels on ubuntu is to wget the deb from http://kernel.ubuntu.com/~kernel-ppa/mainline/ in your case "generic" for amd64 amdgpu.ko on 16.04 is backported from 4.5, so try something newer Hi Michel/Timo I have previously managed to get the system booting (albeit with the same screen issues) but for some reason the newer kernels (I've tried 4.7RC6 and DRM-Next as of today 18th Sept) and both are failing to boot entirely, don't even get to bring up the wired network which I have managed to open a SSH session between two laptops to at least interrogate the non functioning laptop now. Though messing with the kernels seems to have caused some huge corruption on the filesystem through all the system buttoning I'm having to do :) Another reinstall required I think. Is there a specific kernel (maybe not bleeding edge) that I can try? - fyi I also have a Broadcom wireless which is attempting to compile a kernel module during each deb install, I noticed on those two kernels the module failed to compile correctly so might be where the issue is coming from. For reference, I originally posted this on launchpad which has a few more details collected from apport: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-amdgpu/+bug/1597079 Just noticed I did list the kernels I had previously tried in the Ubuntu bug report: v4.7-rc5-yakkety/ v4.4.4-wily/ James, you need to test bleeding edge kernels in order to check if the bug still exists or not.. so grab latest v4.9-rc from the mainline repo to see if it's better Symptoms and hardware appear to be identical to but 97055. I'll let either the bug reporter or someone else with authority mark it as such, though. *** This bug has been marked as a duplicate of bug 97055 *** |
