Release Notes

Cause: Ubuntu 16.04.3 and earlier versions do not contain inbox drivers for PERC 10 and QLogic NICs.
Solution: This issue can be ignored because there is no functionality loss. These components will be supported in a
later version of Ubuntu.
Ubuntu 16.04.3 installer does not recognize the device
name of PCIe SSDs
Description: While trying to install Ubuntu 16.04.3 on PowerEdge 14
th
generation servers, the installer displays the
name of PCIe SSDs as Unknown.
Applies to: Ubuntu 16.04.3
Cause: Udev is responsible for obtaining all the device details, which are not populating the model name for PCIe
SSDs. This leads installer to recognize PCIe SSD disks as Unknown model.
Solution: Enumeration of the disks are correct. A user can differentiate the disks based on enumeration or disk-slot
numbers and proceed with installation.
An error message is displayed during Ubuntu 16.04.3
installation
Description:
During Ubuntu 16.04.3 installation on PowerEdge R640 servers, the following error message is displayed:
Error parsing PCC subspaces from PPCT
Applies to: Ubuntu 16.04.3
Cause: The kernel configuration file has CONFIG_MAILBOX and CONFIG_PCC enabled in Ubuntu by default.
Also, when the BIOS acpi dump was checked the PCCT defines only a "Generic Communications
Subspace" or Type-0 and not Type-1 and Type-2. Whereas the acpi_pcc_probe () takes count of only
these 2 missing/not-defined PCC subspace types.
Solution: This issue can be ignored because there is no functionality loss.
ACPI error messages related to IPMI in Ubuntu 16.04
LTS dmesg logs are displayed
Description:
dmesg displays the following ACPI-IPMI related error messages on system startup:
ACPI Error: No handler for Region [IPMI] (ffff880c04d8c240) [IPMI]
(20110623/evregion-373)
ACPI Error: No handler for Region [IPMI] (ffff880c04d8c240) [IPMI]
(20110623/evregion-373)
Applies to: Ubuntu 16.04.3
Cause:
The DSDT feature of IPMI Op-region is enabled in BIOS, per ACPI 4.0 specifications. Platforms that
require IPMI Op-region enabled in BIOS for Power Meter usage display these ACPI error messages since
the kernel does not have handlers to support the methods in IPMI Op-region.
Solution: This issue can be ignored because there is no functionality loss.
