Subject: [PATCH for 2.6.23] i386: Mark NUMA support experimental
Date: Tue, 21 Aug 2007 14:42:40 +0200 [thread overview]
Message-ID: <20070821124240.GJ32640@bingen.suse.de> (raw)
I did some testing and found quite a lot of problems (doesn't
boot at all on non NUMA and misassigns cores on Opteron systems).
Mark it as experimental and warn against its use for now.
It's still default y for SUMMIT/NUMAQ because it'll presumably
work on these systems.
