** 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!

>02:00.0 Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78) >firmware=36.77d01142.0 backport-iwlwifi-dkms was completly unstable (drop udp packet bigger than somes bytes ) After removing it worked but with slow speed .. Without backport-iwlwifi-dkms, wifi was slow on Focal until the last kernel update. With 5.4.0-31 I recover good performance with over 100Mbs. Before this kernel it was aroud 3-10Mbs/s If I remember well I think built-in wifi was slow since my upgrade to focal ( probably starting with 5.4.0-25) For Focal users , remove backport-iwlwifi-dkms and UPDATE your kernel There is 3 fix for iwlwifi in https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.4.31 and more pending to get into Focal maybe https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.4.33 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.4.36 I have play a lot with driver option to try to recover stability and performance before this kernel update ..
