Hi, folks.
As anybody reading the posts in here carefully may have suspected when I wrote in my previous post, "In particular both Linux editions have not experienced any filesystem problems, in particular like the ones I am seeing now, until kernel 3.2.0-35", the reported EXT4-fs errors are reporiducible on genuine Ubuntu 12.04.1 x64, Unity desktop, as well. - The desktop edition will be irrelevant.
In short words, on
the second machine which I reported about, on /dev/sda5, there is Ubuntu 12.04.1 x64 - Linux Mint 13 x64 is on /dev/sda6.
Sunday at 21:03 kernel 3.2.0-35 was updated to 3.2.0-36. In contrast to the Linux Mint system on the same machine, Ubuntu 12.04.1 survived 2 or 3 reboots runnng on K3.2.0-36 before finally the EXT4-fs error messages started occurring. Yet, once the problem had started it would not go away until after I had reverted to K3.2.0-35 and rebooted twice.
(Remember: the orphaned inodes seem to be left behind during shutdown. So after first rebooting to K3.2.0-35, you will see the EXT-fs error messages caused before this reboot. It is only after the second reboot to K3.2.0-35 that you can hope the errors will not re-occur. And I rebooted several times. Be assured.)
Reproducing the problem on genuine Ubuntu 12.04.1 is important. It suggests that the root cause is not inside Linux Mint. This in turn is important because it will allow me to file a bug report against Ubuntu without even mentioning the term "Mint", because as soon as they read this term, they are likely to turn down the bug report, as if they were unaware of the fact that Linux Mint is 95% Ubuntu plus a different user interface.
Kind regards,
Karl

K3.2.0-35 took back over before 00:44 (Jan 22nd), repaired and was rebooted several times. So far the errors have not re-occured.
Disk Utility (palimpsest) Details:
The controller mode can be got from this
screenshot a few posts above, same result for Mint13 and Ubuntu 12.04.1 of course.
So here is the disk layout, just in case it may be relevant.
