Created attachment 1927913 [details] dmesg output from just before a failed "processors" pm_test. Hi, 1. Please describe the problem: I have an ASUS PN51 mini-pc with an AMD Ryzen 3 5300U CPU. The system fails to resume from suspend. It appears to suspend correctly (display goes off, fan stops, power light blinks), but does not resume (power light becomes solid, fan starts, but no display or keyboard capslock, system is non-responsive and needs a hard boot). Experimenting with /sys/power/pm_test, I find that "freezer", "devices", and "platform" work ok, but "processors" and "core" fail as above. Motivated by this, I find that the system will correctly suspend and resume if I disable non-boot CPUs before suspend, with "chcpu -d 1-7", and then enable them again post-resume. BIOS has been updated to the latest manufacturer version. There don't appear to be any BIOS options related to suspend. 2. What is the Version-Release number of the kernel: 6.0.9-300.fc37.x86_64 3. Did it work previously in Fedora? If so, what kernel version did the issue *first* appear? Old kernels are available for download at https://koji.fedoraproject.org/koji/packageinfo?packageID=8 : I think it used to work several months ago, but it stopped working partway through Fedora 36. I'm afraid I can't be more precise. 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: Reproduces every time, with echo mem >| /sys/power/state 5. Does this problem occur with the latest Rawhide kernel? To install the Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by ``sudo dnf update --enablerepo=rawhide kernel``: Fails in the same way with rawhide kernel 6.1.0-0.rc6.46.fc38. 6. Are you running any modules that not shipped with directly Fedora's kernel?: No. 7. Please attach the kernel logs. You can get the complete kernel log for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the issue occurred on a previous boot, use the journalctl ``-b`` flag. Attached is dmesg from just before a "processors" pm_test suspend. Thanks!
Still failing in Fedora 38 with kernel 6.2.13-300.fc38.x86_64.
