I can confirm that. I got the same oops with 1.4.7pre1. But now with
1.4.7pre2, any file access seems to hang indefinitely.
(Running server and client on same machine, kernel 2.6.24-gentoo-r3,
gcc 4.2.3, on gentoo linux-testing). I downgraded to a cvs checkout
dated 20080222 to regain a working setup.

Reverting delta STABLE14-linux-dont-flush-writes-on-exec-20080326 cures
the hang on 2.6.24 for me.
See below for the state of the hung processes (in D state) when things get
stuck.
