umount /proc/fs/nfsd

Thans  a lot, this was the thing I missed !

Hmm, after this, I left things as the were (nfsd module loaded, but a 0
use count )

I got a BUG while updatedb was running,
(I tried this on a debian machine/kernel)

Same bug on :

cat /proc/self/mounts 

Any luck figuring this out?

I tried reproducing, by stopping everything to get nfsd refcount to
zero:

	# lsmod | grep '^nfsd'
	nfsd                  300025  0 

then running 'cat /proc/self/mounts'.

But I don't see any crash.

This is only 3.1.0-rc1 plus some nfsd patches.

--b.

I'll take a look at this issue later, after my vacations, unless someone
wants to take a look before me ;)

Unfortunately, latest linux tree doesnt even boot on my machine, so I
cannot reproduce the problem right now.

Last message displayed being "Switching to clocksource tsc"

Previous kernels were continuing with :

[    4.448417] 00:09: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
[    4.597727] Real Time Clock Driver v1.12b

Might be a problem with latest tty changes
