problems with xfs 2.6.13 on gentoo

[Kristina Clair <kclair@xxxxxxxxx>]

Hello,

I'm using xfs 2.6.13 on a gentoo linux machine (Linux version 2.6.9
(gcc version 3.3.4 20040623 (Gentoo Linux 3.3.4-r1, ssp-3.3.2-2,
pie-8.7.6)).

We are using hardware raid 5 and lvm to create a 1TB device using xfs,
with usrquota enabled.

There are some actions which seem to partially lock up the filesystem.
 This is the first time I have ever used xfs, and I'm at a bit of a
loss for how to figure out why they are happening.  They include:

xfs_freeze - causes the disk to become completely inaccessible and the
machine to lock up.

setquota - this command actually works for some users, but it
occassionally locks up.  when it does, the processes are impossible to
kill.   is there any command i can use to fix/restore the quota
system?

Please let me know if I should provide any further information, and
thanks in advance for any help!
