Title:
DomU crash on xen <3.2 due to NMI call
Status in “linux” package in Ubuntu:
Fix Released
Status in “linux” source package in Trusty:
Fix Released
Bug description:
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.
