I have the same problem. I don't get this strange behaviour using a cvs from
early May (8-9 May). With a cvs from May 29, some directories and files
get mode 000. Also, some files get 4xxx (suid) and 2xxx (sgid) modes!!!
(very dangerous!!)

All these files are accesed via NFS by normal users.

I must to boot with old cvs kernels.

I begin to see this as soon as I rebooted the machine with the new (May 29) cvs 
kernel.
Another point I want to let you know is that I have the "problem" commented 
early
on the list, "xfs mount warning". Maybe my filesystem was incorrectly unmounted
(not remounted read-only before halt), and then, when booted with new kernel, 
the
recovery has made incorrectly? (it's only a guess...)


TIA & Thanx!
