Infrequent boot failure with 11.1

[Rajil Saraswat]

Hello,

I have a Supermicro X10Dri-T motherboard which refuses to boot 50% of
the time. 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: <ALASKA A M I >
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
