MP-BIOS bug: 8254 timer not connected to IO-APIC

[Kenneth Holter]

Hi list,


The "MP-BIOS bug: 8254 timer not connected to IO-APIC" error message
shows up on boot on at least one of my RHEL servers, and I'm not quite
sure what to make of it. My understanding of the situation is that the
timer is located elsewhere on the motherboard than where the kernel
looks for it. Is this correct?

I've come across people suggestin one should disable APIC by adding
"noapic" to the kernel boot options, but which consequences does this
imply - in SNP setups only one CPU will be used by the kernel?

Best regards,
Kenneth Holter
