Re: smp memory problem

Hello Randy,

The Kernel version is: Linux version 2.6.16-rc3-git3-2-smp

The bluesmoke developer team is also looking into this. See:
http://sourceforge.net/mailarchive/forum.php?forum_id=43090 The archive is
not updated yet. :-( The subject is: smp memory problem with edac

Regards,

Joop Boonen.
