--- Comment #19 from klondike <klondike at klondike.es> ---
In my case this issue (googling for the opcode hanging the GPU lead me to this
bug) was solved by disabling the EFI Framebuffer on the kernel configuration.

If the devs want I can open a second bug to request the Intel GFX drivers
taking over from early framebuffers (for example EFI or VGA) to prevent my
particular issues.
