Hi.
I received the following event with Thinkpad X1 Extreme Gen 2, hence
reporting it as instructed.
Jun 26 18:02:27 superman kernel: thinkpad_acpi: unhandled HKEY event 0x6031

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:

For each line:

For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
When _BCL invalid, disable thinkpad_acpi backlight brightness control.
brightness_enable is already checked at the beginning.
Most new thinkpads are using GPU driver to control brightness now,
print notice when enabled brightness control even when brightness_enable = 1.

I'm experiencing frequent crashes. The laptop has a dual boot
win10/ubuntu20.04, but i work only with Ubuntu. The crash comes always when I
re-launch a command to a virtualbox vms from a terminator shell by pressing
arrow-up (last command from history) and Enter. Here a slice of system.log:
