From 3546e811f13673f2364c15d966a178e8b670cbce Mon Sep 17 00:00:00 2001 From: Olof Johansson Date: Mon, 26 Feb 2007 00:35:14 -0600 Subject: [POWERPC] No DEEPNAP on 970MP 1.0 970MP rev 1.0 is reported to have nonworking DEEPNAP support, we've had bug reports of lockups on those machines. Appearantly Apple used them on some dual-core dual-cpu systems. Rev 1.1 is OK, and that's the one that all 4-way systems seem to use.
