@kaihengfeng I try to use only the most vanilla setup, so yes, it has happened with all the mainline Ubuntu kernels coming from 20 LTS upgrades over the last year and also 22.10.
Suspend is disabled, I guess by kernel parameter `pcie_aspm=off`, by `HandleLidSwitch=ignore` in `/etc/systemd/logind.conf`, and by the fact that I'm using a tiling window manager without any screen timeout. When suspend was enabled with Gnome, the issue did NOT specially affect waking from suspend. It seems to arise randomly. Occasionally the crash is quite hard and freezes the system for 30 seconds. I believe this scenario is when even a reboot is not enough - the card "fails to wake" even on boot. Only a second reboot will fix it (see #18 above for dmesg). Crazy. It's probably unrelated, but here's some dmesg output from very early in boot: [ 0.040179] Kernel command line: BOOT_IMAGE=/vmlinuz-5.15.0-56-generic root=/dev/mapper/vgubuntu-root ro text pcie_aspm=off pcie_port_pm=off [ 0.040374] PCIe ASPM is disabled [ 0.040432] Unknown kernel command line parameters "text BOOT_IMAGE=/vmlinuz-5.15.0-56-generic", will be passed to user space. Is this last line expected? More generally, how would I exclude the possibility of hardware failure? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1882968 Title: ath10k_pci failed to wake target for write32 Status in linux package in Ubuntu: Expired Bug description: Wifi card stopped working.
