Subject: Delays in PCI/ACPI initialization

Dear Linux folks,

Trying to decrease the boot time on a Acer TravelMate 5735Z with Debian 
Sid/unstable and Linux 5.7.6, there are two delays of 100 ms. I created 
a separate issue for each of the delays.

1.  [Bug 208703] PnP ACPI init has 100 ms delay until quirk message
2.  [Bug 208705] New: 100 ms delay in PCI initialization

But maybe they have the same cause, and are duplicates. It’d be great, 
if you took a look.

Kind regards,

Paul
