It has already been patched, though distribution of the patch is pending final
testing by other developers.

I think various of my file-systems are ext4 ...

And given the flakiness of that system, it seems to have withstood the crashes
and lock-ups remarkably well.

That said, I have tended towards ext3 rather than 4 ... :-) (2 is a bit long in
the tooth)

Chers,
Wol

It now seems that it's actually quite a rare occurrence, but it is reproducible,
and if it bites it will bite repeatedly.

If sda3 is mounted on an NFS directory, and that NFS partition is mounted on a
local directory, then you MUST unmount sda3 first.

If you unmount NFS first, then you can't unmount sda3, and corruption is
inevitable if you try to shutdown. The only safe reboot is a big red switch job
on a running system :-(

This seems to be logically impossible to fix :-( but it's unlikely to bite very
many people, and there are workarounds.

Oh - and it affects ALL kernels, and probably more filesystems than ext4.

Cheers,
Wol
