--- Comment #18 from Jérôme de Bretagne <jerome.debretagne at gmail.com> ---
Hello Elizabeth,

The firmware loading error message is unrelated to the actual issue, I've fixed
it by downloading the missing 1.27 firmware binary on my system, but the HP Lap
Dock display is still not properly detected and reboots after a few seconds
when plugged.

I've just attached a newer kern.log file with drm.debug=0x1e parameter set this
time, as you've requested and with firmware 1.27 properly loaded. The output is
much more verbose, let me know if you detect anything useful.

Thanks, Jérôme
