Release Notes
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

Dmesg displays Integrity Measurement Architecture
(IMA) driver related-messages during system boot
Description:
Dmesg displays the following IMA driver related messages during system boot when the TPM 2.0 chip is
enabled with a SHA-256 algorithm:
ima: Allocated hash algorithm: sha1
ima: Error Communicating to TPM chip
Applies to: Red Hat Enterprise Linux 8.1 and later
Cause: The Integrity Measurement Architecture (IMA) driver currently supports the SHA-1 algorithm only.
Solution: Enable SHA-1 as the TPM encryption algorithm only if IMA functionality is required. Otherwise, ignore
these messages and continue using SHA-256 as the TPM encryption algorithm. The error messages do
not indicate any failure with the functionality of TPM2.0. For more information, see Red Hat Knowledge
Base article 5026541.

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
