[lustre-discuss] Problem with 2.16.1 server on Ubuntu Noble 24.04

[Åke Sandgren]

Hi!

I'm trying to get 2.16.1 working on Ubuntu 24.04 (kernel 6.8.0-52-generic Ubuntu)
I have everything built according to the procedure I used when doing this with 2.14 on Ubuntu 20.04 and 22.04.
I.e. after a bit of updating ldiskfs patches I have everything built cleanly.

However, when I try to load lnet it fails and I get this back:
===
[Fri Feb  7 16:10:28 2025] BPF:          type_id=13 bits_offset=256
[Fri Feb  7 16:10:28 2025] BPF:  
[Fri Feb  7 16:10:28 2025] BPF: Invalid name
[Fri Feb  7 16:10:28 2025] BPF: 
[Fri Feb  7 16:10:28 2025] failed to validate module [libcfs] BTF: -22
===

Any ideas for what I managed to mess up?
I can't find anything relevant in master branch that might fix this, so did I mess up my kernel build or is this a new problem?
