Hi Wong,

I tried replicating issue locally on kabylake gen9 platform, however couldn't
succeed. No lspcon probe issue is observed.

Configuration provided by you and mine is:
<Swati>
connector 83: type DP-1, status: connected
DP branch device present: yes
                Type: HDMI
                ID: 175IB0
                HW: 1.2
                SW: 8.41
                Max TMDS clock: 600000 kHz
                Max bpc: 12
<Kai-Heng Feng>
connector 109: type DP-3, status: connected
        DP branch device present: yes
                Type: HDMI
                ID: 175IB0
                HW: 1.0
                SW: 7.35
                Max TMDS clock: 600000 kHz
                Max bpc: 12
Here the difference is in HW and SW f/w. I will recommend you to please update
to the latest sw f/w and test again.
Since Linux F/W Flash Tool is not ready yet to update the f/w, you can update
f/w by booting with windows first and using their AuxUpdate tool.

In the logs of the failed case we can see "Native AUX CH down" and after that
probe issue comes.
May be in the latest s/w f/w issue would have been resolved from the parade, if
this needs a h/w update (which hopefully shouldn't be the case) then nothing
can be done.

So, first update the s/w f/w, test and share your observation; only then we can
take further steps.
