Greg, you might search for a server using xfs filesystems and and a
i586 kernel>= 2.6.33, ( of SLE11-SP1 will serve as well),
log in as an ordinary user, do a "du" on /usr, and wait for the other
users screaming...

I did precisely that, and didn't notice anything special (du on kernel
source tree) kernel, deadline scheduler, 7 drives RAID-6
array, 8GB RAM.

I guess, you're not on this specific openSUSE git version of (e.g.
the preparation for SP1 of SLE11), which, as usual, carries a lot of stuff
from later kernels. The offending patch was included in linux-2.6.33
between -rc4 and -rc5:

xfs: Remove inode iolock held check during allocation

v2.6.33-rc5 (Linux 2.6.33-rc5)

I'm tired.. please ignore this.
