It's a non-critical feature. Support for using MSI on nvidia cards was added in
kernel 3.13, which was why I had suggested trying to disable it.
I guess the rearm register must be somewhere else, or something extra needs to
be done...
OTOH, it's very interesting that you bisected it to that particular commit.
It's not the commit that turns on MSI, but rather a commit that fixes MSI for
some situations, making it more reliable. But apparently not for you...</pre>
