This commit is also breaking boot on one of my boxes; it's causing the
pata_jmicron driver to fail to detect my IDE boot drive. This was
reported in this thread as well:
https://lkml.org/lkml/2012/3/22/6
Apparently, using the 'pcie_aspm=force' may work around the issue, from
some reports that I've seen when searching around. Haven't tried it
myself, yet.
