OK, so I finally managed to bisect the issue down to the following commit. Not much that I can say about it. Someone else suggested that it might all be a question of timing. Might very well be. I will try it out on a system with a different SCSI/RAID controller. The failing system has an "Smart Array 6i" (cciss). "cciss", "ext3" and "jbd" are all modules coming from initrd.
