--- Comment #2 from Michel Dänzer michel@daenzer.net --- Looks like amdgpu_atombios_crtc_powergate_init scribbles over the stack.
(In reply to Carlo Caione from comment #1)
If I recompile the kernel forcing CONFIG_CC_STACKPROTECTOR_NONE == none I don't have the panic anymore (of course) but I can still see the corruption at boot (and weird artifacts on plymouth).
What kind of artifacts in plymouth? Does e.g. X work correctly?
