3534219

Description: On BlueField-3 devices, from DOCA 2.2.0 to 32.37.1306 (or lower), the host crashes when executing partial Arm reset (e.g., Arm reboot; BFB push; mlxfwreset).

Workaround: Before downgrading the firmware, perform:

  • echo 0 > /sys/bus/platform/drivers/mlxbf-bootctl/large_icm

  • Arm reboot

Keywords: BlueField-3; downgrade

Discovered in Version: 32.38.1002

3547022

Description: When unloading the network drivers on an external host, sync1 reset may be still reported as 'supported' although it is not. Thus, initiating the reset flow may result in reset failure after a few minutes.

Workaround: N/A

Keywords: Sync1 reset

Discovered in Version: 32.38.1002

3275394

Description: When performing PCIe link secondary-bus-reset, disable/enable or mlxfwreset on AMD based Genoa systems, the device takes longer then expected to link up, due to a PCIe receiver termination misconfiguration.

Workaround: N/A

Keywords: PCIe

Discovered in Version: 32.37.1306

2878841

Description: The firmware rollback fails for the signature retransmit flow if the QPN field is configured in the mkey (as it only allows the given QP to use this Mkey) as the firmware rollback flow relies on an internal QP that uses the mkey.

Workaround: N/A
