df stuck in tstile

[steve%prd.co.uk@localhost (Steve Blinkhorn)]

I have a pair of identically-configured (except for IP-related and
userland data) 8.0_RC1 servers, with software RAID 1 file systems.
On both of them, df hangs in tsile; on one of the a find coming from
/etc/dail is hung in tstile.   When I configured the systems last
July/August, df did not hang.

Advice please.
