I get complete and total kernel freezes that result in an entirely 
unresponsive system. This issue as driven me entirely insane since it happens 
at random. It has cost me lost work on my machine and I haven't the energy to 
further troubleshoot, since it took me ages to get just this kernel dump via 
netconsole (which didn't always print before dying).
 
System is a 1700X with 2X GFX 803 (RX580)
