Usually, Microcode SW error of iwlwifi happens to occur when the iwlwifi driver doesn't match the FW.
For firmware, Focal uses linux-firmware 1.187.39, which has the newest iwlwifi FW: iwlwifi-QuZ-a0-hr-b0-66.ucode (used by the machine reporting the Microcode SW error.) as the upstream. So we may need to bisect the iwlwifi patches for Focal to see which patch causes the error to happen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2077579 Title: Potential regression: Microcode SW error detected in linux 5.4.0.195.193 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2077579/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
