Subject: [Review 7/7] MCA/INIT Turn off PAL halt
Date: Wed, 17 Aug 2005 05:40:29 +0000	[thread overview]
Message-ID: <7895.1124257229@kao2.melbourne.sgi.com> (raw)

Turn off PAL halt.  For some reason, INIT that is delivered while the
cpu is in PAL halt gets corrupt registers on return from the INIT
handler.  I am still investigating this, for now skip the PAL halt.
