Allegedly not. It merely means that your motherboard is not recognized
as being OK.
My /proc/interrupts (different motherboard) looks like:
CPU0 CPU1
0: 9208532 8999909 IO-APIC-edge timer
1: 49949 49416 IO-APIC-edge keyboard
2: 0 0 XT-PIC cascade
5: 461657 462659 IO-APIC-level es1371, usb-uhci, usb-uhci
8: 61549507 61639660 IO-APIC-edge rtc
9: 308474 307759 IO-APIC-level sym53c8xx
10: 3155516 3157266 IO-APIC-level eth0
11: 173 162 IO-APIC-level sym53c8xx
12: 715163 714417 IO-APIC-edge PS/2 Mouse
14: 48981 49208 IO-APIC-edge ide0
15: 728205 724269 IO-APIC-edge ide1
NMI: 0 0
LOC: 18208803 18208857
ERR: 0
MIS: 0
which tells me that both CPUs are receiving interrupts. Yours should
look similar.
Presumably there are no other errors on your system...
