2590016Description: ibdev2netdev tool is not supported for PCIe PF operating in switchdev mode or on SFs.
Workaround: N/A
Keywords: ibdev2netdev
Reported in version: 3.6.0.11699
2590016Description: A "double free" error is seen when using the "curl" utility. This error is from libcrypto.so library which is part of the OpenSSL package. This happens only when OpenSSL is configured to use a dynamic engine (e.g. Bluefield PKA engine).
Workaround: Set OPENSSL_CONF=/etc/ssl/openssl.cnf.orig before using the curl utility.

For example: 

# OPENSSL_CONF=/etc/ssl/openssl.cnf.orig curl -O https://tpo.pe/pathogen.vim

OPENSSL_CONF is aimed at using a custom config file for applications. In this case, it is used to point to a config file where dynamic engine (PKA engine) is not enabled.

Keywords: OpenSSL; curl
Reported in version: 3.6.0.11699
2407897Description: The host may crash when the number of PCIe devices overflows the PCIe device address. According to the PCIe spec, the device address space is 8 bits in total—device (5 bits) and function (3 bits)—which means that the total number of devices cannot be more than 256.
The second PF maximum number of VFs is limited by the total number of additional PCIe devices that precedes it. By default, the preceding PCIe devices are 2 PFs + RShim DMA + 127 VFs of the first PF. This means that the maximum valid number of VFs for the second port will be 126.
Workaround: Use the maximum allowed VFs on the 2nd PCIe PF of BlueField instead of the maximum of 127 VFs.
Keywords: Emulated devices; VirtIO-net; VirtIO-blk; VFs; RShim
Reported in version: 3.6.0.11699
2445289Description: If secure boot is enabled, MFT cannot be installed on the BlueField DPU independently from BlueField drivers (MLNX_OFED).

Workaround: N/A
Keywords: Server; hang; power cycle
Reported in version: 3.5.0.11563
2581408Description: On a BlueField device operating in Embedded CPU mode, PXE driver will fail to boot if the Arm side is not fully loaded and the OVS bridge is not configured.
Workaround: Run warm reboot on the host side and boot again via the device when Arm is up and the OVS bridge is configured.
Keywords: Embedded CPU; PXE; UEFI; Arm
Reported in version: 2.5.0.11176
1859322Description: On some setups, DPU does not power on following server cold boot when UART cable is attached to the same server.

Workaround: As long as the RShim driver is loaded on the server and the RShim interface is visible, the RShim driver will detect this and auto-reset the card into normal state.

Keywords: DPU; Arm; Cold Boot
Reported in version: 2.4.0.11082
