From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jesse Barnes Date: Tue, 20 Jul 2004 19:44:18 +0000 Subject: [PATCH] sn2 requires a 3.40 or better PROM Message-Id: <200407201544.18841.jbarnes@engr.sgi.com> MIME-Version: 1 Content-Type: multipart/mixed; boundary="Boundary-00=_SYX/AAWbVvmjB+p" List-Id: To: linux-ia64@vger.kernel.org --Boundary-00=_SYX/AAWbVvmjB+p Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Content-Disposition: inline The SGI 3.40 PROM includes a fix for the move of the init_task to region 5, so specify that in sn_sal.h. Unfortunately, the check for the minimum required version happens *after* the hang/MCA that is symptomatic of the bug, so this message also acts as an announcement of the requirement.
