** Description changed: + [SRU Justification] + + [Impact] + + backport-iwlwifi-dkms of latest upstream revision 8324 has no updates + for a few months and is becoming a problem when installed against recent + kernels >= v5.4. It's reported to have poor network throughput for + 7000/8000/9000 series cards. + + [Fix] + + On Bionic and Eoan, we've skipped module install against kernel >= v5.0 + because we have backported drivers for new device models as much as we + can. On Focal and on, the in-tree kernel iwlwifi driver is currently + much more up to date in comparison to backport-iwlwifi-dkms, so there + should be no more reason to install it automatically via modaliases. + + So two actions to be taken here: + * to remove modaliases for the dkms package, so that it won't be installed automatically via "3rd party drivers". + * to mark OBSOLETED_BY kernel 5.4.0 and up + + [Test Case] + + * For new installations, this means backport-iwlwifi-dkms shouldn't be installed automatically even with a PCI id match. + * For existing installations, dkms modules will still be built, but the module installation will be skipped, leaving messages like: + + $ dkms status + backport-iwlwifi, 8324, 5.4.0-33-generic, x86_64: installed + (WARNING! Diff between built and installed module!) (WARNING! + Diff between built and installed module!) (WARNING! Diff + between built and installed module!) (WARNING! Diff between + built and installed module!) (WARNING! Diff between built and + installed module!) (WARNING! Diff between built and installed + module!) + + This can also be tested locally with follow command against packages + prebuilt in https://launchpad.net/~vicamo/+archive/ubuntu/ppa-1863583: + + sudo env AUTOPKGTEST_ARTIFACTS=/tmp debian/tests/dkms-autopkgtest + + [Regression Potential] + Low.
