I can confirm this bug with a Precision 5540 with vanilla 5.4.11. 

In kernel 5.1.x I was able to adjust my backlight by poking intel_backlight in
sysfs. After updating to 5.3.x I lost this ability. I believe there is a
regression here.

The ACPI messages appear to be an independent issue from the backlight control
issue. I've always gotten the ACPI messages, even when backlight control used
to work correctly.

I have tried building a kernel with CONFIG_ACPI_CUSTOM_METHOD and following
Zhang's instructions. There was no change in behavior.
