Bios bug on all recent MSI notebooks. Please set kernel parameter
pci=realloc

Worked perfectly. Thank you.

How did you set the kernel parameter to that?

In debian/ubuntu you edit the file /etc/default/grub.
Use either of those variables: GRUB_CMDLINE_LINUX_DEFAULT, or GRUB_CMDLINE_LINUX.
Then run sudo update-grub - reboot.

For a one-shot testing you can select your kernel version and press “e” in the grub menu at boot time and edit the parameters for just that one particular boot.
