GPU 1: Allocating buffers failed with: clCreateBuffer (-4)
  Fatal error. Restarting...
happens with all cards, 1,2,...
I have 3 same rigs, only one does this!
Anyone know what is the problem? Cards are RX470, 8gb. Tried many drivers and last 3 versions of PM.

Nevermind, -gser  fixed it!

edit: no, just another error, something "kernel unknown"?
