Hi Marta, I am assuming this issue is with KVM switch for display (which are upgraded to latest KVM FW) ? - Shashank

From IRC: <marta_> tsa, shashank wanted to know if KVM switch FW was upgraded for fi-cfl-s2, could you reply in: https://bugs.freedesktop.org/show_bug.cgi?id=104056 ... <tsa> marta_: fi-cfl-s2 is not connected to kvm switch

Based on the latest GFX QA results this failure is still visible 62 times on CFL. Triggered by several cases from kms_atomic_transition, kms_cursor_csc, kms_cursor_legacy and kms_flip.

Triggered by several cases from kms_atomic_transition, kms_cursor_csc, > kms_cursor_legacy and kms_flip. QA has only provided link for BXT results on this CNL only bug. I am however, totally fine with QA re-opening the bug.

How did CI resolved this on their side? 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. (having this, issue is not a blocker or Highest Critical yet)

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.
