[SOLVED] modprobing a kernel module gives error: "could not insert 'iw_cxgb4': Invalid argument"

[reckless]

Trying to load the Chelsio iWarp module using this command: modprobe iw_cxgb4. I get the following error:

ERROR: could not insert 'iw_cxgb4': Invalid argument

This is the dmesg output:

[  +0.090486] BPF:[104824] STRUCT ata..percpu

[  +0.000011] BPF:

[  +0.000014] failed to validate module [libcxgb] BTF: -22

Modinfo on both modules that I need to load:

Any idea how to fix this so I can load the iw_cxgb4 kernel module?

is it possible you have booted using the PVE 6.x 5.11.22-4-pve, but are on PVE 7.x?

I'm actually not sure - how do I check and make sure?

I'm certainly on Proxmox version 7 and did a full upgrade from Proxmox 6 a week ago. I think it built the kernel during the upgrade.

 

[fabian]

could you upgrade to the -5 kernel and see if the problem persists if you boot into that one?

Hi Fabian, can you specify which kernel version you mean exactly? I just rebooted and here's screenshots from the console output:



Currently I can only select from these kernels:

pve-kernel-5.11.22-5-pve

Updating to that kernel seemed to fix it, thanks Fabian. Modprobing both cxgb4 and iw_cxgb4 returns without errors.
