It hangs with the message DMAR: Found table at 0x7995ccb0 x2APIC should be disabled by DMAR table but already enabled by BIOS; enabling. Event timer "LAPIC" quality 600 ACPI APIC Table: Package ID shift: 5 L3 cache ID shift: 5 L2 cache ID shift: 1 L1 cache ID shift: 1 Core ID shift: 1 I have tried setting X2APIC on and off in the BIOS but it hasnt helped. I also custom compiled the kernel without the option EARLY_AP_STARTUP. The full log is at https://pastebin.com/FUdUKaR2 Anybody has a idea what could be the issue? Thanks
