Subject: Suppress APIC errors on UP x86-64.
Date: Thu, 23 Feb 2006 20:42:28 -0500 [thread overview]
Message-ID: <20060224014228.GB16089@redhat.com> (raw)
Quite a few UP x86-64 laptops print APIC error 40's repeatedly
when they run an SMP kernel (And Fedora doesn't ship a UP x86-64 kernel
any more). We can suppress this as there's not really anything we
can do about them.
