[Test Case] Tested on Dell XPS 13 9310. No longer has this regression and both WiFi/Bluetooth works fine as before. [Where problems could occur] The actual firmware downloading process is moved into a state machine callback that has identical semantics with before. Additions or removals to this in the future may change the timing of fw being dowloaded. [Other Info] While the commit causing this regress is backported to 5.11 onward and fixed in v5.12 and 5.13, leaving Hirsute is the only victim. ========== original bug report ========== See these references for more information: - https://bugzilla.kernel.org/show_bug.cgi?id=213055 - https://bugs.archlinux.org/task/70849 Can you please prevent this already fixed bug from being introduced any further into Ubuntu.
