** Description changed: Bluetooth does not work on Ubuntu 24.04 machines running with AMD Ryzen AI processors. The only workaround is booting into BIOS, disabling Bluetooth, rebooting, booting back into BIOS, and re-enabling Bluetooth in BIOS. All other troubleshooting methods fail to work. Currently 4 systems have been affected: 2 computers with AMD Ryzen AI 9 HX PRO 370 w/ Radeon 890M & 2 computers with AMD Ryzen AI 7 PRO 350 w/ Radeon 860M After a few hours/days of use with a fresh install of Ubuntu 24.04 the Bluetooth toggle grays out and is unable to be turned on or used despite rebooting or restarting the Bluetooth service.
