No it isn't!! But I think that would be the problem. I just realized
that [after you wrote this] that I turned on 'parallel' execution in my
Gentoo init scripts for both of those systems.
Tonight, I am going to change hdparm so that it runs xfs_freeze on all
fs's just before tuning, and [of course un-freeze] to see if that cures it.
thanks,
Joshua
