Bug Description

== Comment: #0 - Harish Sriram
--Problem Description---
kernel does not detect interface in Ubuntu, driver missing in kernel

Contact Information = <email address hidden>

---Issue observed---
While installing Ubuntu on a machine with Chelsio card, ubuntu-installer fails to show the interface name - probable cause would be due to missing driver in Ubuntu kernel.

Machine Type = Tuleta/Power 8 BML

----Additional Info-----
Installer Shell
-------------------
BusyBox v1.27.2 (Ubuntu 1:1.27.2-2ubuntu3) built-in shell (ash)

Step to reproduce: Install Ubuntu 18.04 on a BML with Chelsio card interface UP.

---Expected---
Kernel to detect the interface.

---Actual---
Installation fails as interface is not detected from the card.

What is the config option that needs to be switched to have this enabled in the installer kernel?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.15 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

There are a few steps that need to happen:
1) determine which kernel modules are required for that hardware
2) check if those kernel modules are build and available from the regular userspace package
3) check if those kernel modules are included in the udeb kernel package for the installer
4) check that installer correctly detects and loads those missing modules and/or said udebs are included in the d-i built itself.

If I am reading the provided debug output right, "cxgb4" driver is required. I see that there is

kernel/drivers/net/ethernet/chelsio/cxgb4/cxgb4.ko

built in the regular kernel build, and shipped in the -extra package.
(there are a few others as well e.g. iw_cxgb4, cxgb4i, cxgb4vf)

However, I do not see net/ethernet/chelsio/* included in the nic-modules-4.13.0-32-generic-di_4.13.0-32.35_ppc64el.udeb package as used by the installer.

Therefore I believe the scope of this bug is to make sure that net/ethernet/chelsio/* is shipped in the nic-modules udeb package.

Then a d-i rebuild will be needed.

Then the bug reporter can re-validate if this issue becomes resolved.

What is the next steps on this? Do we get "cxgb4" driver added as part of installer and it gets resolved in next build? If so any target date?

I have sent a patch to the mailing list. That means an udeb package will be built when a new bionic kernel is released. Then, when a new d-i image is built with that new kernel, it will be possible to test it.

Or if you can provide the fix (patched kernel) as well work out for us to validate internally.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
