	Ok Ted. An easier way was to use Systemrescuecd beta which
provides e2fsck 1.42.6. Now the problem has gone ;)

	No problem. I always compile my software, so the first time I
notice it was after upgrading to 3.7.0 kernel. Anyway I'm not sure if
it appeared after the upgrade to 3.7.0 kernel.

	But ok. If I have some more of these issues, I will report here.

	Thanks for the great support!
