We failed to detect hotplug events caused by chamelium within the time-out.

If this is an actual kernel issue that means we may not have reliabile hotplug, i.e. connecting external screen may yield no effects.

This bug appeared only on a single chamelium system [fi-kbl-7567u], which uses lspcon.

    status: connected
    to: HDMI
    via: MC2800 v1.76
    display: STM AthenaDP

It may be LSPcon, it may be Chamelium, it may be IGT or it may be kernel, hard to tell.

Since the low occurrence (2 time in 2 months and then nothing), I'll move to to medium (having to do two hotplugs every quarter is annoying but not that serious), and we can close it after 7 more months.
