Re: 2.6.17-mm5

[Andy Whitcroft <apw@shadowen.org>]

Seems that we have some kind of schedular balance panic, I want to say
back as this seems very familiar.  Seems to be affecting the multi-node
NUMA-Q systems here.  The single node ones appear unaffected.

Nothing jumps out of the patch list.  Any suggestions as to what to rip
out :)
