Public bug reported: Last working version: 5.13.0-20-generic Not working: 5.13.0-21-generic
Notebook: Dell XPS 15 Wifi adapter: Qualcomm QCA6390 Wireless Network Adapter [AX500-DBS (2x2)] (rev 01) After booting 5.13.0-21-generic the wifi adapter is not detected anymore (missing from lspci). I have to turn off the computer and boot an older kernel. Simple restart doesn't work. With 5.13.0-20-generic the driver is just loaded fine: lsmod | grep ath11k ath11k_pci 24576 0 ath11k 413696 1 ath11k_pci qmi_helpers 28672 1 ath11k mac80211 1024000 1 ath11k cfg80211 892928 2 ath11k,mac80211 mhi 73728 2 ath11k_pci,qrtr_mhi ProblemType: Bug DistroRelease: Ubuntu 21.10 Package: linux-image-5.13.0-20-generic 5.13.0-20.20 ProcVersionSignature: Ubuntu 5.13.0-20.20-generic 5.13.14 Uname: Linux 5.13.0-20-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.11-0ubuntu71 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: tim 17241 F.... pulseaudio CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Date: Wed Nov 10 15:02:43 2021 InstallationDate: Installed on 2021-11-01 (9 days ago) InstallationMedia: Ubuntu 21.10 "Impish Indri" - Release amd64 (20211012) MachineType: Dell Inc.
