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 [1]: https://bugzilla.kernel.org/show_bug.cgi?id=208703 [2]: https://bugzilla.kernel.org/show_bug.cgi?id=208705
