I faced the same issue with 25.04 after installing linux-modules- iwlwifi-6.14.0-24-generic.
The 'linux-modules-iwlwifi-6.14.0-24-generic' package supplies its own 'mac80211' module, which exports the above listed incompatible symbols 'ieee80211_sta_register_airtime', etc. >>> $ apt-file list linux-modules-iwlwifi-6.14.0-24-generic ... linux-modules-iwlwifi-6.14.0-24-generic: /lib/modules/6.14.0-24-generic/ubuntu/iwlwifi/mac80211.ko.zst ... <<< When modprobing 'mt76', the newly added 'cfg80211' and 'mac8211' modules are loaded, instead of the ones that came with the linux- modules-6.14.0-24-generic package. >>> $ modprobe -v mt76 insmod /lib/modules/6.14.0-24-generic/ubuntu/iwlwifi/cfg80211.ko.zst insmod /lib/modules/6.14.0-24-generic/ubuntu/iwlwifi/mac80211.ko.zst insmod /lib/modules/6.14.0-24-generic/kernel/drivers/net/wireless/mediatek/mt76/mt76.ko.zst modprobe: ERROR: could not insert 'mt76': Invalid argument <<< As the version information of '/lib/modules/6.14.0-24-generic/ubuntu/iwlwifi/mac80211.ko.zst' and the generic module '/usr/lib/modules/6.14.0-24-generic/kernel/net/mac80211/mac80211.ko.zst' differ, the load fails. If your modprobe shows the same, you could try the following. (1) Unload the newly added modules 'mac80211' and 'cfg80211' (2) Manually insmod the generic modules 'mac80211', 'cfg80211', and 'mt76' In my case purging the linux-modules-iwlwifi-6.14.0-24-generic package solved the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1947364 Title: mt76 module disagrees on a lot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1947364/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
