I have just been to dells site and there are firmware updates for almost 
every component in the system released about 2 weeks ago (10-11/4).  I 
have around 17 [12]950's waiting to go into pre production testing at 
the moment so I think that I will spend some time upgrading the firmware 
on them now rather than later.

Thanks for the heads up.
