ext4 recovery/deleted orphans on reboot...

In Ubuntu 12.10 pre-release, I've frequently been observing ext4
recovery has been needed after reboot [1].

This clearly isn't expected, however could be a side-effect of eg
incomplete flushing after unmount before the ACPI/cf8 reset vector is

So, is this thought to be a kernel issue or userspace? I'm using a
256GB Samsung 830 SSD, but was seeing this on an OCZ Vertex 3
(Sandforce) SSD also.

Many thanks,
