Greetings!
I have a Dell PowerEdge 1550 running 4.2-STABLE that gives the following
warning upon boot up:
APIC_IO: Testing 8254 interrupt delivery
APIC_IO: Broken MP table detected: 8254 is not connected to IOAPIC #0 intpin 2
APIC_IO: routing 8254 via 8259 and IOAPIC #0 intpin 0
What exactly is this telling me? And should I be concerned? I'm evaluating
this machine for my employer so I'd like to get as much information as
possible.
Thank you!
Here is the machine's dmesg:
