[Bug 445852] Re: SSD stall during boot

[Raf]

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.
