dmesg - different kernels

## Observation

openQA test in scenario sle-15-SP5-Online-KOTD-x86_64-install_ltp+sle+Online-KOTD@64bit fails in
[install_ltp](https://openqa.suse.de/tests/9526246/modules/install_ltp/steps/88)

## Test suite description
Maintainer: pcervinka


## Reproducible

Fails since (at least) Build [5.14.21-150500.12.1.g25f225f](https://openqa.suse.de/tests/9515612)


## Expected result

Last good: (unknown) (or more recent)


## Further details

Always latest result in this scenario: [latest](https://openqa.suse.de/tests/latest?arch=x86_64&distri=sle&flavor=Online-KOTD&machine=64bit&test=install_ltp%2Bsle%2BOnline-KOTD&version=15-SP5)


Test scenario fails after KOTD installation and reboot, system under system has no ip assigned. Manually verified behavior in vm with different kernels on the same vm image:

15-sp4 KOTD  5.14.21-150400.639.gad373ba-default  works OK
15-sp5 (latest milestone)  5.14.21-150400.24.18-default works OK
15-sp5 KOTD 5.14.21-150500.14.gc80fb26-default fails

dmesg shows for 15-sp4-KOTD and 15-sp5 "eth0: link becomes ready", line is missing in dmesg for 15-sp5 KOTD (no link is reported by ethtool too).

Comment 1 Petr Cervinka 2022-09-16 08:48:09 UTC

Same result is also on aarch64  https://openqa.suse.de/tests/9525986#step/install_ltp/3  (no ip assigned on eth0)

Comment 2 Martin Doucha 2022-09-16 09:19:28 UTC

There's CONFIG_VIRTIO_NET=m in the kernel config but virtio_net.ko.zst appears to be missing in the RPM.

Sorry, you're right.

Comment 5 Thomas Bogendoerfer 2022-09-17 11:04:09 UTC

I've missed a change in a merge commit during backport. Fix commit is now on my for-next branch.

has a kernel with the fix included.
