This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- trusty' to 'verification-done-trusty'. If the problem still exists, change the tag 'verification-needed-trusty' to 'verification-failed- trusty'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Impact] * Ubuntu trusty images can't be used on some NVMe-based cloud instance types. * Mainline commit a522905 "NVMe: Always use MSI/MSI-x interrupts" fixes the issue; application of this to 3.13 requires a set of prerequisite patches, and a minor backport. a522905 NVMe: Always use MSI/MSI-x interrupts e32efbf NVMe: make setup work for devices that don't do INTx be577fa nvme: Use pci_enable_msi_range() and pci_enable_msix_range() 42f6142 NVMe: per-cpu io queues 4f5099a NVMe: IOCTL path RCU protect queue access 5a92e70 NVMe: RCU protected access to io queues [Test Case] * Verify that a trusty-based image can boot on the affected instance type. [Regression Potential] * This change set affects all users of the NVMe driver, so regression potential is moderate to high. Additional soak testing may be warranted before merging this patch set. * The patched NVMe driver has been exercised by Dan Streetman, and given the thumbs-up.
