Subject: [PATCH] - Initialize sched domain table
Date: Fri, 23 Jul 2004 01:02:57 +0000 [thread overview]
Message-ID: <20040723010257.GA27350@sgi.com> (raw)
Here is a trivial patch that is required to boot the latest 2.6.7 tree
on the SGI 512p system.
Initial the busy_factor in the sched_domain_init table.
Otherwise, booting hangs doing excessive load balance
operations.
