>From the logs, I can see that:
HDMI-A-2 gets detected during the boot-up
HDMI-A-2 gets modeset of 1360x768
Then it gets a hot-unplug ( I guess this is the manual unplug)
While disabling the PIPE, the PIPECONF register times out.

Can you please provide this register's value (0x70008), when you see this
error?
./intel_reg read 0x70008

As this error has shown up on HDMI hot-unplg, Does the display ever come-up, in
the consecutive hot-plus, after we see this timeout error?
