I need to enable x2apic on Intel(R) Xeon(R) CPU E3-1225 v5 @ 3.30GHz, and I find x2apic was supported in cpuinfo:
But when kernel started, I find error message:
[ 0.138328] IRQ remapping doesn't support X2APIC mode, disable x2apic.
I have checked my kernel config:
CONFIG_X86_X2APIC=y
What can I do to fix this problem?
