Subject: [patch 069/198] x86_64: disable interrupts during SMP bogomips checking
Date: Tue, 12 Apr 2005 03:31:40 -0700 [thread overview]
Message-ID: <200504121031.j3CAVkkR005403@shell0.pdx.osdl.net> (raw)
From: Andi Kleen <ak@suse.de>
Port over a i386 kludge from rusty to x86-64
I don't think it is a full solution, but the upcomming smp bootup rewrite
will solve it.
This fixes BUGs at bootup on bigger x86-64 systems.
