Comment 2 for bug 1814919

For reference last good build on 4.19.0-12.13 kernel

https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-disco/disco/amd64/d/dpdk/20190205_000700_24c9f@/log.gz

We have two dkms modules
1. dpdk-igb-uio (still working)
2. dpdk-rte-kni-dkms (the failing one)

From the log:
ERROR (dkms apport): kernel package linux-headers-5.0.0-3-generic is not supported
Error! Bad return status for module build on kernel: 5.0.0-3-generic (x86_64)
Consult /var/lib/dkms/dpdk-rte-kni/18.11/build/make.log for more information.

I ran the same in a local KVM autopkgtest with disco against ppa:canonical-kernel-team/unstable.
From there I have the detailed failure of the dkms build:

I wanted to take a look at 18.11.1 anyway - it is not out yet - but maybe there is a fix in it.
