The latest if possible, but the one your patch applies to if I have no

So can't this be fixed?

Yes, but it's useless because of the abysmal (absence of) speed. And
all the VM problems... The machine I need raid50 on is a central
server, if it stops everything else goes down. In fact I'm not using
2.4 on it precisely because of the VM/raid problems!! :-( :-(
If I can't do raid50 on our server I'll have to resort to raid10,
losing 50% of our so expensive disks...
