It needs to be pr_debug() to avoid allowing a guest to spam the host 
logs.  But I don't think it will help in this case.  There's probably a 
bug under low memory conditions that causes the guest to execute 
incorrectly, and it just happened to hit this bug.  I don't think it's 
really related to the ioapic.
