Request from Amazon:
Our engineering team has reported that the kernel in 14.04 LTS is making
a call to NMI which in turn causes DomU instances to crash under Xen
<3.2. This affects only a particular range of kernel versions from
3.12.25 to 3.15.6, and the kernel in 14.04 seems to be 3.14.x. There is
already a patch in the mainstream kernel version to apply that would
address the situation. The probability of a DomU crash with the current
ubuntu 14.04 kernel on a Dom0 running Xen <3.2 is always. Our customers
sometimes run on instance types that route them to >3.2 Xen so this does
not impact all customers.
** Affects: linux-meta (Ubuntu)
Importance: High
Status: Confirmed
