Unable to create or modify namespace for NVDIMM
Description When you create or modify a namespace for NVDIMM, it fails.
Applies to SUSE Linux Enterprise Server 15
Workaround Use the "--no-autorelabel" option while creating or modifying the namespace. For example:
● Creating namespace—#ndctl create-namespace -r region0 -m raw -f --no-
autolabel
● Modifying namespace—#ndctl create-namespace --mode raw -e namespace0.0 -f
--no-autolabel
Solution The issue is resolved in SUSE Linux Enterprise Server 15 SP1
Systems affected All yx4x Dell EMC PowerEdge systems that have NVDIMM installed.
NOTE: The PowerEdge servers are represented using the generic naming convention. To identify the
range of server models, see Identifying the series of your Dell EMC PowerEdge servers on page 26.
Tracking number 119207
Dell EMC PowerEdge AMD Server is not booting to OS
after enabling the SME/SEV feature
Description
After you install SLES 15 on Dell PowerEdge AMD Server and then when you try to boot into OS with
kernel boot parameter mem_encrypt=on, server does not boot. This kernel boot parameter enables the
AMD SME/SEV feature. This behavior is seen when OS is installed on PERC VD. Also, PERC VDs are not
detected during SLES 15 OS installation, when you pass kernel boot parameter mem_encrypt=on.
Applies to SUSE Linux Enterprise Server 15 SP1
Workaround To fix the issue, download the kernel from https://ptf.suse.com/a4508678dc8ee2c11453898fb347f199/
sles15-sp1/18216/x86_64/20190830/.
Solution The issue is resolved in SUSE Linux Enterprise Server 15 SP2, SUSE Linux Enterprise Server 15 SP1
Maintenance Update kernel-default-4.12.14-197.18.1 version and later. For more information, see SUSE
Linux Enterprise Knowledge Base article 000019539.

Tracking number 134814
When system reboots, system stops responding at
the end of the reboot process
Description
When the system reboots, system stops responding at the end of the reboot process. When the system is
in this state, it does not respond to keyboard or mouse device and iDRAC virtual console displays the No
signal message.
Applies to
SUSE Linux Enterprise Server 15 SP1
Workaround
To recover the system, perform any one of the following:
● Using iDRAC GUI, on the Dashboard page, click Graceful Shutdown drop-down, and then select
Reset System(warm reboot).
● Restart the system by pressing the Power button.
Solution Update system BIOS to 1.4.8 version.
Systems affected PowerEdge R6515, PowerEdge R6525, PowerEdge R7515, and PowerEdge C6525
