Running a 3.13 kernel, built from upstream git repository (commit
d8ec26d7f8287f5788a494f56e8814210f0e64be).

I'm able to consistently generate an ongoing interrupt storm by [un]docking my
Lenovo W530 when using the nouveau driver.  This problem was first noticed
under a 3.10 kernel and associated nouveau driver.  I then switched to the
above 3.13 kernel for the MSI interrupt support and to see if the problem
persisted.

The attached nouveau.interrupts is the output of read_interrupts, the source
for which is here: <a href="http://www.darnok.org/xen/read_interrupts.c">http://www.darnok.org/xen/read_interrupts.c</a>.  This file
shows the interrupts generated during 5 second intervals.</pre>
