Whenever doing a warm boot (reboot), kernel 4.4.6 crashes showing the stack
trace in the attached picture. The kernel boots fine when doing a cold start or
after pressing the reset button.
The GPU in question is a "PNY Quadro FX 580" (Tesla / G96) with two attached
monitors, both connected on display port.
The crash happens quite early when the kernel sets mode on the framebuffer.
Resolution is set to 1920x1200 px, 240x75 cols/lines.
