description |
I upgraded overnight from Wily to Xenial. The system will not boot. Only a blank screen after grub loads the kernel.
The recovery kernel loads fine and I was able to find the following messages:
[drm] VGACON disable radeon kernel modesetting
[drm:radeon_init [radeon]] *ERROR* no UMS support in radeon module!
The recovery kernel command line had a nomodeset parameter that was not in the main kernel command line.
Adding the nomodeset parameter the main kernel command line finally booted the system. It's kind of ugly but it seems to work.
Note: For what it's worth I reported a similar issue against several Utopic kernels (bug #1407505). There was a back and forth with jsalisbury until a kernel finally worked. I have had no problems until today.
Hope that helps. |
