I am having an intermittent issue with the RX Vega 64 in my box on Linux
4.15-rc1.  Sometimes everything boots up and starts fine.  Other times, it
boots to monitors with the backlight lit and nothing on the display (blank
startups).

During these blank startups, I get a series of BUGs in the output.  The first
one looks like this:

Sometimes a power-cycle will boot to a good display, sometimes it won't.  I am
currently on 8 bad boots in a row.  At lunch my 4th boot worked.

I have Xorg disabled on this device right now so it appears to be limited to a
kernel issue.
