I'm running now a vanilla 3.6.3 + your patch.

After a lot of file operations (Gentoo emerging, kernel build, git
pulls, ...) I s2disk the system (that with the external USB drive)
yesterday, wake it up today, rebooted it -
and had to manually repair the file system, because the automatic fsck
gave up.

Most of what landed in /lost+found however were only temp data of
installing a Gentoo package at 14th of September - so nothing
seriously lost AFAICS.

Nevertheless there's another Linux system I have (64bit RH EL,internal
drive), where with kernel 3.5.4-1.el6.elrepo.x86_64 EXT4 errors occurred.
I attached the whole appropriate section of /var/log/message.
