I am however, totally fine with QA re-opening the bug.

CFL seems really green on CI. What is different on the CI machine? Firmware updates? Are the logs here updated, or should we collect new logs on top of new drm-tip? LSPCON warns are seen again on ww07.1 but not as many like ww05, warning on link issue is very sporadic having a prove that in ww06, warns went away. also Shashank has confirmed it is sporadic and also has been seeing in KBL Platform with same LSPCON chip.

New FW in testing on CI now. Latest results? (In reply to steven.j.hockemeier from comment #24) > Latest results? With the new firmware, this is working well. However, we still need to distribute this firmware and a flasher to go with it. Maybe we could duplicate this bug to a generic LSPCON flasher bug, but we have not created it yet. In the mean time, we should keep this bug open. |
