Hi Kevin, the first thing that comes to mind, after a look at the logs and the commits, is regarding this
On my board, where everything works ============================================================ ubuntu@localhost:~$ sudo dmesg | grep DMI [ 0.038850] DMI: https://www.mellanox.com BlueField SoC/BlueField SoC, BIOS BlueField:3.9.10-2-ge2bd2430ac Jun 10 2025 ubuntu@localhost:~$ sudo i2cdetect 1 WARNING! This program can confuse your I2C bus, cause data loss and worse! I will probe file /dev/i2c-1. I will probe address range 0x03-0x77. Continue?

The failure happens for the following code: ============================================================================================ "drivers/net/ethernet/mellanox/mlxbf_gige/mlxbf_gige_main.c" 28 #define MLXBF_GIGE_ACPI_TABLE_VERSION 2 ..... 308 static int mlxbf_gige_probe(struct platform_device *pdev) ..... 330 if (version != MLXBF_GIGE_ACPI_TABLE_VERSION) { 331 dev_err(&pdev->dev, "ACPI table version mismatch: expected %d found %d\n", 332 MLXBF_GIGE_ACPI_TABLE_VERSION, version); 333 return -EINVAL; 334 } ============================================================================================ Probably this has a direct impact with this bug. Would it be possible for you to upgrade the BIOS of the BF board? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2140758 Title: oob interface has gone after upgrading the linux-bluefield To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-bluefield/+bug/2140758/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
