Driver dependency mismatch errors reported while
installing out-of-box drivers on Red Hat Enterprise
Linux 8.x
Description: Driver dependency mismatch errors are reported when inst.dd installation methods (flash drive, driver
package, HTTP, NFS, FTP) are used to install the out-of-box (OOB) drivers during operating system
installation. The dependency errors are not observed after the initial installation as the operating system
will use the out-of-box (OOB) drivers. The issue is industry wide and is not specific to Dell EMC
PowerEdge servers.
Applies to: Red Hat Enterprise Linux 8 and later
Workaround: Block the installation of the inbox versions of the OOB drivers.
Systems
affected:
Dell EMC PowerEdge yx4x and yx5x servers
Tracking number: 176624
Dmesg displays TPM and nvdimm related-messages in
Red Hat Enterprise Linux 8.1
Description:
When Red Hat Enterprise Linux Version 8.1 is booted with the TPM 2.0 chip enabled, dmesg displays the
following messages in var/log/message:
No TPM handle discovered.
failed to open file /etc/ndctl/keys/nvdimm-master.blob: No such file or
directory
There is no impact to the functionality of the TPM chip if it is enabled in the system BIOS. This is a
cosmetic error and can be ignored.
Applies to: Red Hat Enterprise Linux 8.1 and later
Systems
affected:
Dell EMC PowerEdge yx4x and yx5x servers
Tracking number: 164988
Link Up message is observed when the NVMe device
slot is powered off and the device is unplugged
Description:
The message Link Up is observed in the dmesg log when the NVMe device slot is powered off and the
device is unplugged by running the following command:
echo 0 > /sys/bus/pci/slots/<slot number>/power
The expected message is Link Down because the device is unplugged.
Applies to: Red Hat Enterprise Linux 8.0 and later
Cause: This is due to an issue with the pciehp driver.
Workaround: This issue is a cosmetic issue and can be ignored. The NVMe device is recognized when plugged into the
slot.

affected:
