RHBA-2016:0549 - Bug Fix Advisory

Topic

Updated s390utils packages that fix one bug are now available for Red Hat Enterprise Linux 7.

Description

The s390utils packages contain a set of user-space utilities that should be used together with the zSeries (s390) Linux kernel and device drivers.

This update fixes the following bug:

• Previously, due to a bug in the cpuplugd daemon initialization script, the Cooperative Memory Management (CMM) kernel module was not automatically loaded when necessary. As a consequence, hot-plugging memory could be performed only after manually loading CMM. This has been fixed, and now it is possible to hot-plug memory without manually loading CMM. (BZ#1309628)

Users of s390utils are advised to upgrade to these updated packages, which fix this bug.
