Then, let's do some testing.
Could you please do the following:
- Boot the system with acpi_backlight=vendor
- sudo echo 0 >/proc/sys/kernel/nmi_watchdog
- cat /proc/sys/kernel/nmi_watchdog (make sure the output is 0)
- Try changing the brightness using the keyboard keys, and see whether
a freeze would happens or not.
Note that if you just put echo 0 >/proc/sys/kernel/nmi_watchdog in
/etc/rc.local, then you are going to need to reboot the system in order for the
script to be executed.
If a freeze still happens, then my guess is that there is another source of
NMIs on your system other than nmi_watchdog that still conflicts with the
vendor firmware backlight driver.
