Hi! I just wanted to let you know that one of the desktops I use for testing no longer seems to boot after this commit (just finished bisecting and confirming). The machine hangs before it gets to fbcon, and the error I'm seeing in the early boot console is as such:
Kernel panic - not syncing: timer doesn't work through Interrupt-remapped IO-APIC CPU: 0 PID: 0 Comm: swapper/0 Not tainted 6.8.0-rc5Lyude-Test+ #20 Hardware name: MSI MS-7A39/A320M GAMING PRO (MS-7A39), BIOS 1.10 01/22/2019 Call trace: <TASK> dump_stack_lvl+0x47/0x60 panic+0x340/0x370 ? timer_irq_works+0x67/0x130 panic_if_irq_remap+0x1d/0x20 setup_IO_APIC+0x82d/0x950 ? _raw_spin_unlock_irqrestore+0x1d/0x40 ? clear_IO_APIC_pin+0x16c/0x260 apic_intr_mode_init+0x5d/0xf0 x86_late_time_init+0x24/0x40 start_kernel+0x673/0xa90 x86_64_start_reservations+0x18/0x30 x86_64_start_kernel+0x96/0xa0 secondary_startup_64_no_verify+0x180/0x18b </TASK> --- [ end Kernel panic - not syncing: timer doesn't work through Interrupt-remapped IO-APIC ]---
Assuming I copied this over by hand to my computer correctly, the decoded backtrace should be:

Happy to provide any more information from this machine if you need it :). And hopefully i'm not just late to the party and reporting a regression someone else found already lol
