Can't boot anymore without noapic

[Stefan Friesel]

5.19.0-43 was the last kernel that I could boot just fine, without noapic. The ones after that (-45 and -46) won't boot and display nothing at all. They must have a kernel panic related to IO-APIC very early on in the boot because adding panic=10 reboots the system after 10 seconds. I tried adding earlyprintk=efi,keep but even then I get no messages. With noapic the kernel does work.

System is a Ryzen 5 1400 on a B350 chipset mainboard
