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: http://www.darnok.org/xen/read_interrupts.c. This file shows the interrupts generated during 5 second intervals.
