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
Red Hat Enterprise Linux 7.6 and later
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 8.2
Systems affected All Dell EMC PowerEdge servers
Tracking number 151479, 152995, 152997
After system reboot, Disk data format (DDF) devices
are not listed in /proc/mdstat
Description:
Disk data format (DDF)-based MD virtual disk (VD) devices are not listed in the /proc/mdstat file, if
there are more than one MD VD devices, after rebooting the system.
Applies to:
Red Hat Enterprise Linux 7.6 and later
Cause: Not available
Workaround: After creating the MD VD devices and before rebooting the system, run the following command:
mdadm --detail --scan >> /etc/mdadm.conf
NOTE: Verify the file before system reboot to confirm that the MD VD devices created earlier are
not altered.

error is displayed. This issue occurs when the drive firmware receives a request to activate immediately
without reset. This message is not observed when you update the firmware using a Dell-provided
firmware update package. There is no functionality loss.
Applies to: Red Hat Enterprise Linux 8.1
Cause: Not available
Solution: The issue is resolved in Red Hat Enterprise Linux 8.2
