Subject: [PATCH] sn2 requires a 3.40 or better PROM
Date: Tue, 20 Jul 2004 19:44:18 +0000 [thread overview]
Message-ID: <200407201544.18841.jbarnes@engr.sgi.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 347 bytes --]
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.
