I've had to hard-reset my machine.

It is like git reset --hard but not very functional.



Sometimes mount will cause a freeze of the / directory with remote 
(network) filesystems.

And sometimes you can only recover by hard-resetting the machine.

And then upon reboot, you try the same thing, and no issue at all.

(Thank you Harald)

I mean, maybe it has nothing to do with NFS or SMBD, but....

I run into this regularly and as such, have regular (perhaps not as 
often, depends on how much you need to do it) complete system freezes.

So do you have any info on whether someone else could fix it? I mean, 
there must be kernel people that know about it right. Is there a way to 
file the issue with some bug tracker or something? Somewhere people will 
notice?

The CIFS mount hangs for some reason and the entire system goes down 
with it.

And every process that needs to read the / directory, hangs.

And that's your Linux stability, then :S.

This can also happen on a server that has an NFS mount.

I suppose the reading of / fails because the stat on the mountpoint 
fails (blocks).

So it's probably not only going to be a hanging mount(), but also a 
subsequent hanging stat().

Serious issue for me.
