Ref #	Issue
3654930	Description: If the DPU BMC firmware has been upgraded from version 2.8.2-x or older to version 23.03 or newer, it is necessary to execute a factory reset of the DPU BMC.
	Workaround: N/A
	Discovered in version: 23.04
3591305	Description: Soft reset of BlueField Arm cores is not graceful reboot.
	Workaround: N/A
	Discovered in version: 23.07-3
3587968	Description: VLAN 4040 serves as a dedicated VLAN for facilitating Redfish communication between UEFI and DPU BMC. However, if the OOB RJ45 port is connected to an unmanaged switch or hub, the VLAN traffic from VLAN 4040 may spill over into the broader LAN network which may lead the local UEFI to unintentionally communicate with a remote BMC instead of the intended local BMC.
	Workaround: Ensure that the RJ45 OOB port is connected to a switch port capable of isolating this internal communication traffic from the broader LAN network.
	Discovered in version: 23.07-3
3560559	Description: If the DPU OS's OOB interface is disabled, it may lead to an issue that results in the DPU BMC losing network connectivity. This problem arises when the UEFI enables the OOB port (e.g., PXE, Redfish), but the OS does not load the necessary services and OOB kernel driver. In this scenario, the physical link remains active despite the OS driver not functioning, causing the hardware queue to become filled. Consequently, flow control pause packets are sent to the onboard 3-port switch, which may eventually lead to the DPU BMC losing its network connectivity.
	Workaround: Configure the 3-port switch to disable flow control support by running the following from the DPU BMC shell: Copy Copied! `i2ctransfer -y 10 w4@0x5F 0x21 0x08 0x01 0xe1 i2ctransfer -y 10 w4@0x5F 0x11 0x08 0x0d 0xe1`
	Discovered in version: 23.07-3
3566036	Description: After performing BF BMC factory reset, the /home/root/.ssh directory is deleted which causes the first attempt to confirm the host identity and initiate a BFB update procedure to fail while displaying the error message: Copy Copied! `"Host is unknown"`
	Workaround: Reattempt confirming the host identity and initiating the BFB update procedure.
	Discovered in version: 23.07-3
N/A	Description: If the NIC BMC boots with non-default network configuration under /run/initramfs/rw/cow/etc/systemd/network/*, then the dedicated VLAN 4040 which supports the Redfish host interface with the UEFI BIOS device is not created.
	Workaround: Remove the network configuration files and reboot the system by running the following: Copy Copied! `rm -f /run/initramfs/rw/cow/etc/systemd/network/*`
	Discovered in version: 23.07-3
3561677	Description: It is not possible to modify the values of the BootOrder, BootOverride, and Secure Boot attributes from the UEFI menu because they are set by default to be configured from Redfish interface.
	Workaround: To directly modify these attributes from the UEFI menu, the user must disable the Redfish option in the UEFI menu.
	Discovered in version: 23.07-3
3388059	Description: When BlueField-2 boots and its services are loaded, there is a possibility that the IPMI over RMCP may become unresponsive due to the default timeout for commands being set to 1 second.
	Workaround: Increase the default timeout to 4 seconds when sending IPMI RMCP commands using the -N option. Example command: Copy Copied! `sudo ipmitool -I lanplus -C 17 -N 4 -H <BMC IP> -U <BMC User> -P <BMC password> mc info`
