<pre>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.
display:
DP-1:
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.
