Description Marta Löfstedt 2018-03-19 14:04:23 UTC
Since bug 103558 has such big impact for the KBL shards. I don't want that many test to be covered on this machines as well, so I start this new link training bug for the BAT machines link training et. al. issue.

Update: this issue has been reproduced with APL NUCs when using HDMI output.

New FW in testing on CI now.

Still happening with latest FW 1.75 in every round of IGT/CI_DRM/Drmtip execution

As seen from dmesg- happening for parade.

Comment 11 ashutosh.dixit 2019-11-01 18:54:50 UTC
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.

Comment 15 Lakshmi 2019-11-08 14:16:57 UTC
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.
Comment 16 Jani Saarinen 2019-11-08 14:35:22 UTC
Agree, no lspcon on this tgl
