I don't think that there is a bug in upstart. More likely the increased parallelism of upstart triggers a bug in the kernel, firmware, or hardware.

If it is a kernel bug, it has been in the kernel for several releases. I have tested with 2.6.29-rc3 (and most versions in between), that is the oldest kernel on http://kernel.ubuntu.com/~kernel-ppa/mainline/ that can still boot my ext4-karmic partition.

I am wondering if #61 is not on to something. However, my SDD is ATA, not SATA (so no NCQ anyway). I will research if the SDD can do TCQ, and if yes how to disable it. That would suggest a firmware/hardware bug.
