Precision Tower 3620 BIOS Update 2.32.0 Discussion

Hello,

after upgrading from 2.8.1 to 2.32.0, my HP Mellanox NIC

    Mellanox Technologies MT27520 Family [ConnectX-3 Pro]
    Subsystem: Hewlett-Packard Company Ethernet 10G 2-port 546SFP+ Adapter

is not recognized by Linux 6.8.12 anymore.

When adding acpi=off to the kernel flags, the NIC is working again but I have only 1 thread/CPU (core) remaining instead of two which negatively affects the virtualization performance.

Error messages:

Any thoughts? I tried downgrading the BIOS - with 2.8.1 it is working again but with 2.13.1 it is not so the issue was already introduced earlier...
