Booting with `pci=nobios` fails on Dell XPS 13 9360

[Paul Menzel <pmenzel@xxxxxxxxxxxxx>]

Dear Linux folks,


On the Dell XPS 13 9360/0596KF, BIOS 2.21.0 06/02/2022, booting Linux 
6.9-rc5-00036-g9d1ddab261f3 with `pci=nobios`, the internal keyboard 
does not work, and there are DRHD (IOMMU) errors and intel-lpss errors 
printed by Linux. (As the keyboard does not work, I am unable to enter 
the LUKS passphrase, and capture the Linux messages.)

Is that option supposed to work, and should Linux be able to detect and 
configure itself without the help from the system firmware?


Kind regards,

Paul
