Public bug reported: Description: Ubuntu 22.04.4 LTS Release: 22.04
I have tried upgrading to various kernels supported in 22.04: - linux-image-5.17.0-1035-oem - linux-image-6.2.0-39-generic - linux-image-6.5.0-35-generic - linux-image-6.5.0-1023-oem None of these kernels work with my QCA6390 wifi adapter on my Dell XPS 9310. I cannot connect to my access point, it fails to associate. v5.17 kernels report that the hardware rfkill switch is activated (there is no such switch on this laptop). 6.x kernels simply fail to connect to the AP. Additionally the bluetooth interface which part of the same chip will stop working. I have tried upgrading the firmware from https://github.com/kvalo/ath11k-firmware/ but this hasn't helped at all. Firmwares tried for ath11k/QCA6390: - ath11k_pci 0000:72:00.0: fw_version 0x101c06cc fw_build_timestamp 2020-06-24 19:50 fw_build_id - ath11k_pci 0000:72:00.0: fw_version 0x10121492 fw_build_timestamp 2021-11-04 11:23 fw_build_id I am currently using the 5.15-generic kernels, they've worked very well, including with the upgraded firmware. I have also tested 23.10 and 24.04 live images, neither will connect to my access point. I'm unable to test a mainline kernel as my system uses ZFS and it's tricky to add that module without having to recompile a kernel from scratch. ** Affects: linux-meta-oem-6.5 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2065938 Title: QCA6390 won't work with any kernel above 5.15 in 22.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-meta-oem-6.5/+bug/2065938/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
