Subject: linux-2.6-rt patch on ppc and OOM messages
Date: Wed, 29 Mar 2006 07:45:51 +0100 (BST) [thread overview]
Message-ID: <20060329064551.29548.qmail@web25913.mail.ukl.yahoo.com> (raw)
Dear All,
Is Ingo Molnar's realtime-preempt patch compatible
with ppc, or is there any work on a porting effort of
this patch ? I have made some tests on a 85xx machine
with this patch, under heavy load on ethernet
interfaces, thw system prints OOM messages on console
and hangs..
Thanks.
