        <pre>I can confirm the same effect for R9 270X + Dell U3415W connected via
DisplayPort.

The other monitor (Dell 2007WFP) connected via DVI works fine.

Latest kernel tested: 4.5.0-rc3-00071-g17a5cd3

Don't know if its related but I also see this every boot:

radeon 0000:01:00.0: Invalid PCI ROM header signature: expecting 0xaa55, got
0x8b00

[drm:si_dpm_set_power_state [radeon]] *ERROR*
si_restrict_performance_levels_before_switch failed

Also note that this is the same card as in #76490.</pre>
