Does this issue occur on any other platform? or just on the LSPcon con port of a BXT RVP?
This platform is where I catched the issue with 100% reproducability. I don't think I've seen exactly the same problem with other hosts.
Hello, is this issue still valid with latest drm-tip? Thank you.
First of all. Sorry about spam. This is mass update for our bugs. Sorry if you feel this annoying but with this trying to understand if bug still valid or not.
