The DAG epoch issue: it seems AMD fixed it for Vega in drivers and now they are working on Polaris. New drivers will be available soon, may be in two weeks or so.
I highly doubt this - not that Vega doesn't have the issue (I would hazard a guess the massively different memory controller fixed it without them needing to try), but them fixing it for Polaris - ESPECIALLY in that time frame, doesn't sound right to me.
I'm not going to call it, because my sources haven't gotten back to me on this, but I don't think so.
I admit it - my gut was wrong.
- issue is due to large page sizes, and since AMD now knows what the issue is, a fix is probably in the pipeline after all.
