My laptop is an Akstron 1417, and every time I press Fn+F5 (Volume up), it rapidly increases the volume and then it locks my keyboard. It won't type anymore. The same happens when decreasing the volume.
If I switch volume keys from gnome-settings to F5, the volume works just fine.
This happens on every linux distro. The same issue is not present when installing/running Windows 10.
I have also added acpi_osi=linux, acpi_backlight=vendor, acpi_osi_name=Linux but none of them seem to work.
