error message "CPU0: local APIC error 0x40"

Hi,

As titled, I can find that error message in dmesg everytime my laptop boots.
Any ideas? Or is this a hw/sw bug?

Oh, hmm.  It seems it happens as a side effect of something in ACPI.  Error 
bit 0x40 means an interrupt message was sent to the CPU with an illegal vector 
(< 32).  It is most likely a harmless bug in your BIOS.  Can you get a
verbose
dmesg to narrow down when the error occurs?
