Tested the mainline build v7.0.14 (7.0.14-070014-generic from kernel.ubuntu.com/mainline, same upstream base as 7.0.0-38). Only linux- image-unsigned + linux-modules were installed, so the nvidia module isn't present for that kernel; the only taint before suspending was W from an unrelated fs/exec.c path_noexec warning (gnome-shell) at boot.
1. WoWLAN off, power-button wake: resumes normally. 2. WoWLAN on, power-button wake: same failure as on the Ubuntu kernel. Display comes back, then the system freezes (input dead, clock stopped) about 50 ms after resume. Same sequence in the log: ath12k_wifi7_pci 0000:09:00.0: Unable to change power state from D3hot to D0, device inaccessible qcom_mhi_qrtr mhi0_IPCR: PM: failed to resume early: error -22 ath12k_wifi7_pci 0000:09:00.0: failed to set mhi state: RESUME(7) ath12k_wifi7_pci 0000:09:00.0: failed to wakeup from wow: -110 ath12k_wifi7_pci 0000:09:00.0: wmi command 16387 timeout (followed by the same mac80211 WARNINGs) So it reproduces upstream. Kernel log of the mainline cycle attached (MAC addresses masked). ** Attachment added: "resume-wowlan-mainline-7.0.14.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2170503/+attachment/6008480/+files/resume-wowlan-mainline-7.0.14.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2170503 Title: ath12k WCN7850: system hangs on resume from suspend when WoWLAN magic- packet is enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2170503/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
