System crashes when rebooted with SR-IOV-enabled
QLogic cards
Description When the system is rebooted with SR-IOV-enabled QLogic cards, the system crashes and generates a
coredump (vmcore) in /var/crash.
Applies to
SUSE Linux Enterprise Server 15 SP1
Cause: The system crash is due to an issue in the qede driver.
Workaround Disable SR-IOV before rebooting the system. To disable SR-IOV, run the following command:
echo0 > /sys/class/net/network inteface name/device/sriov_numfs
Solution: The issue is resolved in Red Hat Enterprise Linux 7.8 and later. For more information, see Red Hat
Enterprise Linux Knowledge Base article 4991311.
Systems affected All Dell EMC PowerEdge servers
Tracking number 151479, 152995, 152997
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.
Applies to: SUSE Linux Enterprise Server 15 SP1
Cause: Latest updates in the ipmi driver allow ipmi driver to unload, though the /dev/ipmi is in use by
userspace 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 resetablished.
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.
Systems
affected:
Dell EMC PowerEdge yx4x and yx5x servers
Tracking number: 155847
Systems with the AMD Rome processor display a CCP
and PSP initialization failure messages in dmesg
Description:
Systems with AMD Rome processor display the following messages in dmesg:
● CCP initialization failed
● PSP Initialization failed
The PSP message indicates its dependency on the SEV feature.
The CCP message indicates that the CCP device is not available.
Applies to: SUSE Linux Enterprise Server 15 SP1.
Solution: This issue is resolved in SUSE Linux Enterprise Server 15 SP2.
