Comment 64 for bug 2009136

As a workaround until the fix lands (and is subsequently back-ported to the jammy HWE kernel), Koba's test-kernel in comment 36 works nicely. However, please note that the test kernel is not signed and will require that you disable secure boot to try it (if it's enabled on your machine), which may or may not fit your circumstances. If you require secure boot to be enabled I'm afraid you'll need to wait a bit longer.

If you don't require secure boot, then:

* disable secure boot
* grab all files from the link in comment 36 to a clean directory
* sudo dpkg -i *.deb (from that directory)
* (you likely don't actually need *all* of the packages, but rather than sorting out which you do / don't need it's easier to simply install the lot)
* sudo reboot
