I've added the HWE kernel (7.0.0-31-generic; though there's an upgrade waiting to be installed). Bluetooth works without problems in this kernel. That has an advantage over moving back to 138 because, presumably, they've fixed security vulnerabilities. Instructions to install HWE are here: https://ubuntu.com/kernel/docs/reference/hwe- kernels/#installing-a-hwe-kernel
HWE also solves another problem in 139 for me -- I was unable to resume from hibernation. On the other hand, it introduced a problem, endless error messages of "ACPI Error: Aborting method \_GPE.PL6E due to previous error (AE_NOT_FOUND)" that fill up my / directory (error occurs after hibernate, wake, suspend, wake). I 'fixed' this by adding acpi_mask_gpe=0x6E to my grub cmdline. So far, I've seen no problems from the mask. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2165873 Title: Bluetooth fails to initialize due to a kernel NULL pointer error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2165873/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
