[Bug 1839750] Re: 40% performance loss in Mesa with Linux 5.0
Tested additional mainline kernels installed via UKUU. 4.19.66 LTS worked great. So did 4.20.17, the last in its series. The performance regression appeared when I tested 5.0.3, and as noted above, still persists in 5.2.8. This may be a mainline kernel bug, but I'll leave it open here for further input. I'm a complete layman in this area. ** Description changed: Mesa's RADV performance has dropped nearly 40% across multiple applications since upgrading my HWE kernel to 5.0.0-23.

This issue persisted with the 5.0.0-25 kernel update. I later tested again after updating Mesa to 19.0.8.
