I xfs_repair'd that disk a week or so back, and have been fine until today when..

(16:22:57:root@zerosum:tmp.6)# ll
ls: cannot access : No such file or directory
total 0
?????????? ? ? ? ?            ? ?
(16:22:58:root@zerosum:tmp.6)# cd ..
(16:23:06:root@zerosum:tmp)# rm -rf tmp.6
rm: cannot remove ‘tmp.6’: Directory not empty
(16:23:14:root@zerosum:tmp)# cd -
/home/davej/src/trinity/tmp/tmp.6
(16:23:23:root@zerosum:tmp.6)# stat *
stat: cannot stat ‘\020’: No such file or directory

I don't know if this is residual crap from that first problem that never got fixed up,
or something new.

Any ideas ?
