On the Dell XPS 13 9300, there is a two second hang during kernel boot due to
some ACPI issue. I understand that a similar warning has been reported in the
past and has been dismissed as "harmless." However, in my case, the "Linux
query ignored" issue causes a two second hang on boot, which seems not quite
harmless. I am running the Dell XPS 13 9300, with the latest firmware. I have
also tried many variations of the acpi_osi kernel parameter and nothing seems
to change anything. 

I understand that this is possibly a firmware bug rather than an ACPI one, but
it seems to me even if it is the laptop manufacturer's issue, ACPI should be
able to determine that and continue in less than two seconds, in a similar
~50ms timeframe that this issue has been resolved in in the past.

Please see the attached dmesg for more context. The issue happens at the jump
from the 0.48 to the 2.49 second mark.
