From: Jan Kiszka <[EMAIL PROTECTED]>
KVM-x86 dumps a lot of debug messages that have no meaning for normal
operation:
- INIT de-assertion is ignored
- SIPIs are sent and received
- APIC writes are unaligned or < 4 byte long
(Windows Server 2003 triggers this on SMP)
Degrade them to true debug messages, keeping the host kernel log clean
for real problems.
