I'd be really dubious about that.  Our pa8900 ... the most mm unstable
system we have ... is running -rc5 just fine.  The only warning before
boot is the usual SMP one.

Linux ion 2.6.28-rc5 #20 SMP Tue Nov 18 18:16:35 PST 2008 parisc64

Why don't we compare configs?  This is mine for ion:

I suspect we have some nasty interaction in the device driver subsystem
(ion, the pa8900, isn't running either USB or PDC stable).
