System BIOS reports that system was reset due to timeout from operating system (OS) watchdog timer

Description

On systems when: Software Raid Dell PowerEdge RAID Controller S150/S140 is enabled

8

Fixes

SLES 15 SP3 installed OS watchdog timer is enabled in system BIOS The system BIOS reports that system was reset due to timeout from watchdog timer when the system is rebooted gracefully.
Following message is displayed in BIOS Power On Self Test (POST):
UEFI0082: The system was reset due to a timeout from the watchdog timer. Check the System Event Log (SEL) or crash dumps from Operating System to identify the source that triggered the watchdog timer reset. Update the firmware or driver for the identified device.

Workaround

The message can be ignored as the system reboots gracefully. The issue can be worked around by disabling OS watchdog timer in system BIOS.

Solution

The issue is resolved in SUSE Linux Enterprise Server 15 Service Pack 3 maintenance update kernel version kernel-default-5.3.18-150300.59.98.1.

Systems affected All Dell PowerEdge servers

Zoning changes on SFSS not reflected in the host

Description Workaround Solution Applies to

NVMe-oF Transport Control Protocol (TCP) zoning changes made on Dell SmartFabric Storage Software (SFSS) that remove access to I/O controllers on NVMe subsystem are not reflected in the host.
The host service stacd, a part of the nvme-stas package, automatically connects to the I/O controllers returned in response to the get log page command . Each I/O controller is represented as a Discovery Log Page Entry (DLPE) in response to the get log page command. When a zoning change is made on SFSS to remove access to one or more I/O controllers, the change is ignored and is not applied by the stacd service. stacd continues to connect to the I/O controllers returned by the existing DLPEs.
Disconnect relevant controllers: 1. Remove all connections between the host and subsystem:
nvme disconnect -n
2. Remove only a single connection between the host and subsystem:
nvme disconnect -d
The issue is resolved in nvme-stas 1.1.6. If the desired behavior is to disconnect I/O when an associated zoning change is implemented, the following changes are needed: # vi /etc/stas/stacd.conf sticky-connections=disabled # systemctl reload stacd SUSE Linux Enterprise Server 15 Service Pack 4

The version field in the output of the modinfo command for certain networking drivers is null

Description

PowerEdge servers with the AMD Rome processor fail to detect an NVMe drive after multiple hot plugs

Description
Cause Workaround

The PowerEdge servers with the AMD Rome processor fail to detect an NVMe drive after multiple hot plugs.
Issue in pciehp driver.

NOTE: The output of each command varies based on your system configuration.

Follow the steps: 1. Identify the parent device to which the NVMe device is connected using the following command:

lspci -t

-+-[0000:e0]-+-00.0

|

+-00.2

|

+-01.0

|

+-02.0

|

+-03.0

|

+-03.1-[e2]—-00.0

From the above snippet, the device e2:00.0 is the NVMe device and the device e0:03.1 is the parent device. The parent device is used for the steps that are described subsequently. 2. Read the Slot Status Register in the PCI Express Capability structure by running the following command:
setpci -s e0:03.1 CAP_EXP+0x1a.w

Output: 0148 (value returned) 3. Clear the event bits that are impacted by running the following command:
setpci -s e0:03.1 CAP_EXP+0x1a.w=0x0108

Fixes

4. Re-read the Slot Status Register to confirm that event bits are cleared by running the following command:

setpci -s e0:03.1 CAP_EXP+0x1a.w

Output: 0040 (value returned) 5. Unplug the drive and then plug-in the drive after clearing the event bits.

Component updates in systems with iSM installed on SUSE Linux Enterprise Server 15 SP1 operating system generates watchdog timer expired messages

Description

Firmware updates performed using Linux DUP files with iSM running in the background generates watchdog timer expired events in the Lifecycle Controller log files.

Cause

Latest updates in the ipmi driver allow ipmi driver to unload, though the /dev/ipmi is in use by user space tools. Firmware DUPs try reloading the ipmi driver while running. Running Linux DUPs breaks the iSM connection with iDRAC and causes iDRAC to register the connection break after a timeout. After the firmware update is completed, the iSM connection with iDRAC is reestablished.

Solution

The issue is resolved in SUSE Linux Enterprise Server 15 SP2, SUSE Linux Enterprise Server 15 SP1 Maintenance Update Kernel 4.12.14-197.34.1 version and later. For more information, see SUSE Linux Enterprise Server Knowledge Base article 000019602.

Booting into operating system fails on systems with TPM 1.2 chips

Description

On systems with TPM 1.2 chips, booting into operating system fails when TPM Security field is set to On without Pre-boot Measurements in BIOS.

Cause

When the option On without Pre-boot Measurements is set in BIOS, the shim utility cannot write to TPM PCR registers. Shim considers this as a fatal error and fails to boot.

Workaround

In BIOS, set TPM Security field to On with Pre-boot Measurements.
