*** Bug 103026 has been marked as a duplicate of this bug. ***
Note duplicate of 103026 is only due to link training issues. The lockdep was solved from 4.14.0-rc3.
Is this a LSPCON port on CFL? Not sure if this is LSPCON related issue or another DP timeout issue on CFL. Manasi
This can be a LSPCON issue, so it needs testing with my patchset https://patchwork.freedesktop.org/series/31639/ Only when this patch series is merged, we would be able to comment on if this is a new issue, or one among the existing ones. - Shashank

This system needs still fw update.

Marta, Can you please confirm that the LSPCON FW version is 1.70 not 1.63 and older ? Cat /sys/kernel/debug/dri/0/i915_display_info Look for connector DP-1/2 (where we have LSPCON attached) There would be branch device info like this: > DP branch device present: yes > Type: HDMI > ID: MC2800 > HW: 2.2 > SW: 1.63

I haven't been able to update the FW
Thanks for the confirmation Marta. We need to test this issue with LSPCON FW V1.70, as this issue is fixed on several KBL devices using this FW version. - Shashank

SO, NO this and no other of the cfl-s bugs have so far not affected cfl-s2.
I meant to say: "CFL-S now replaced with CFL-S2, is this issue seen there."
So was this seen only on Old FW version (1.63) and not surfaced later?
(In reply to Jani Saarinen from comment #23) > So was this seen only on Old FW version (1.63) and not surfaced later? Again this bug was for the old cfl-s, this bug was archived from cibuglog when cfl-s was replaced with cfl-s2. The similar bug for cfl-s2 is bug 104056
OK, resolving this then.
