This bug is awaiting verification that the linux- bluefield/5.15.0-1008.10 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy' to 'verification- done-jammy'. If the problem still exists, change the tag 'verification- needed-jammy' to 'verification-failed-jammy'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

The MDIO GW lock is set after read. Make sure to always clear to indicate that the GW register is not being used. If the lock is mistakenly interpreted as ACTIVE, then subsequent MDIO accesses will be blocked and PHY device will be inaccessible. [Fix] For each MDIO read and write transaction, the last step should be to clear the MDIO GW lock. [Test Case] Boot the BlueField-2 platform Bring up the "oob_net0" interface via DHCP or static IP Ping and file transfer over "oob_net0" should work properly Bounce the "oob_net0" interface a few times and repeat tests [Regression Potential] * Low risk for causing a regression, tested well in our lab.
