Public bug reported: latest ubuntu-kernels stop responding to usb storage devices all using xhci_hcd:
- Prolific Technology, Inc. PL2773 SATAII bridge controller maybe others too. Symptom: devices are shown in thunar, nautilus. They show up in /dev as /dev/sdXN, but clicking them in thunar or nautilus only gives the message "Pending operation". "mount" will never finish. Trying to access these devices directly using kernel functions, the called function never comes back. A system shutdown will never finish. I've tried some more recent kernels on a non-zfs system with same results: - linux-5.15.0-rc1-x86_64 - linux-5.14.3-x86_64 - linux-5.13.16-x86_64 - linux-5.10.64-x86_64 ProblemType: Bug DistroRelease: Ubuntu 21.04 Package: linux-generic 5.11.0.34.36 ProcVersionSignature: Ubuntu 5.11.0-34.36-generic 5.11.22 Uname: Linux 5.11.0-34-generic x86_64 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair ApportVersion: 2.20.11-0ubuntu65.3 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: tps 1991 F.... pulseaudio CasperMD5CheckResult: pass Date: Wed Sep 15 05:26:30 2021 InstallationDate: Installed on 2021-09-14 (0 days ago) InstallationMedia: Xubuntu 21.04 "Hirsute Hippo" - Release amd64 (20210420) MachineType: LENOVO 20FAS16K00 ProcEnviron: LANGUAGE=de_DE TERM=xterm-256color PATH=(custom, no user) LANG=de_DE.UTF-8 SHELL=/bin/bash ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/BOOT/ubuntu_eo9ngl@/vmlinuz-5.11.0-34-generic root=ZFS=rpool/ROOT/ubuntu_eo9ngl ro quiet splash vt.handoff=1 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon.
