This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Disabling the bluetooth subsystem reduces the amount of security-sensitive code we have to worry about in the cloud kernels and also has the nice side effect of minimizing build times and kernel sizes. The cloud kernels known to have bluetooth enabled include: * [B/D/E] linux-aws (arm64 only) * [X/B/D/E] linux-gcp * [B] linux-gke-4.15 * [B] linux-gke-5.0 * [X/B/D/E] linux-oracle [Test Case] 1. Install patched kernel and reboot into it 2. Ensure that the following command does NOT display any output: $ grep CONFIG_BT=[my] /boot/config-$(uname -r) [Regression Potential] There could be an unexpected dependence on bluetooth within one of the clouds but I think it is highly unlikely.
