Bug assessment: the following bugs are all related: bug 103313, bug 105602, bug 108833 and bug 108131 (with the same "LSPCON mode hasn't settled" error message).

This bug continues to happen frequently, 39% repro rate (despite FW updates). If we are ignoring the bug should we decrease the priority so we don't have to assess it often? Copying Shashank/Swati.

There are similar failures as in this bug on TGL as well. For TGL, a separate issue created bug 112233. Let's keep this bug for KBL/LSPCON.

Jani Saarinen @jani.saarinen said:

Agree, no lspcon on this tgl
