Perform a Yum Update When Using Oracle Linux UEK Kernel
Important Operating Note
When using the Unbreakable Enterprise Kernel Release 4 Update 4 (UEK R4u4) with Oracle Linux 7, perform a yum update to obtain the latest UEK R4 release updates. Oracle Server X8-8 requires Unbreakable Enterprise Kernel version 4.1.12-94.5.7 or later.
For more information and instructions for updating Unbreakable Enterprise Kernel Release 4, refer to the Unbreakable Enterprise Kernel web site at: http://docs.oracle.com/cd/E93554_01/ .

Linux MMIO Kernel Configuration Can Affect Oracle Hardware Management Pack fwupdate Tool for Intel NIC/LOM Updates
Important Operating Note
On systems running Linux with Intel network interface cards or LAN-on-Motherboard (LOM) controllers, if MMIO memory access is set to strict access in the Linux kernel (iomem=strict or as part of the kernel build configuration) you will see the following message in syslog/dmeg when running the Oracle Hardware Management Pack fwupdate tool:
kernel: Program fwupdate tried to access /dev/mem between c4a00000->c4a01000. (Address may vary)
This message is expected and should not cause an issue with the operation of the
operating system. There will be one message each time fwupdate is run
and the kernel is in strict MMIO access mode.
However, when the kernel is running in this mode, fwupdate will not
be able to access Intel-based network controllers to either list information or update
firmware.
For more information on this issue including a workaround, see the "Linux MMIO Access
Settings Can Affect fwupdate Commands On Intel Network Controllers"
section in the Oracle Hardware Management Pack 2.4 Server CLI Tools User's
Guide at:
