[Bug 2060437] Re: The module ib_ipoib does not load automatically on ubuntu server 24.04

Hi @shangsong2,

Sorry for the late reply.

I'm not an expert in IB, but after some investigation it seems that the
module ib_ipoib as being a ULP (Upper Layer Protocol) does not get
loaded automatically by the presence of any hardware interface. It needs
to either be loaded manually or by some boot services.

In Ubuntu this functionality seems to be provided by the 'rdma-core'
package, which provides the systemd service 'rdma-hw.target', which in
turn should load all the modules from the following file, amongst
others, containing by default the 'ib_ipoib' module:

/etc/rdma/modules/infiniband.conf

Could you please install the 'rdma-core' package, reboot the system and
check whether the modules are loaded?
