[Bug 1968604] Re: rtl8761b usb bluetooth doesn't work following reboot until unplug/replug
The firmware is NOT loaded correctly... the "bu" file is loaded instead of the "b" I used to have Ubuntu 21.10 and my Bluetooth USB dongle was loading rtl8761b_fw.bin. Last week I upgraded to Ubuntu 22.04 and since then I can not use my USB dongle, it connects my Sony headphones and immediately disconnects, connects, disconnects, ... Using sudo dmesg | grep Bluetooth, I saw [ 10.106036] Bluetooth: hci0: RTL: examining hci_ver=0a hci_rev=000b lmp_ver=0a lmp_subver=8761 [ 10.107035] Bluetooth: hci0: RTL: rom_version status=0 version=1 [ 10.107038] Bluetooth: hci0: RTL: loading rtl_bt/rtl8761bu_fw.bin [ 10.108050] Bluetooth: hci0: RTL: loading rtl_bt/rtl8761bu_config.bin [ 10.108170] Bluetooth: hci0: RTL: cfg_sz 6, total sz 27814 So kernel 5.15 loads different firmware rtl8761bu instead of rtl8761b used by kernel 5.13 in Ubuntu 21.10. I guess this is a kernel bug. As a workaround I made symbolic links and now my Bluetooth USB dongle works fine: /lib/firmware/rtl_bt$ ls -al *8761* lrwxrwxrwx 1 root root 19 Apr 10 06:32 rtl8761bu_config.bin -> rtl8761b_config.bin lrwxrwxrwx 1 root root 15 Apr 10 06:32 rtl8761bu_fw.bin -> rtl8761b_fw.bin -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1968604 Title: rtl8761b usb bluetooth doesn't work following reboot until unplug/replug To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1968604/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1911055] Re: [modeset][nvidia] suspend/resume broken in nvidia-460 : Display engine push buffer channel allocation failed
Reporting a nVIDIA issue in an Ubuntu bug report is probably not as efficient as contacting nVIDIA directly. I made a report in the Linux forum: https://forums.developer.nvidia.com/t/460-56-no-desktop-on- resume-from-suspend-to-ram/170275 but I did not get a response yet. Could some of the people affected by this bug add their nvidia_bug_report.log.gz ?

@Alf HP Lund: you use Kubuntu.
