So, now I could find a little more detail about my issue: I tested with other mainline kernel from 5.15 series and the problem started with 5.15.5
And it is also present on 5.15.10 and 5.15.24 (thats what I have also tested) STR works with 5.15.0, 5.15.3, 5.15.4 (thats what I have tested) After knowing the version I could find this on the net: https://www.reddit.com/r/pop_os/comments/radfeg/psa_kernel_5155_and_intel_6th_gen_cpus_issue_with/ And so after adding intel_iommu=off as kernel option STR works also with linux-image-5.15.0-18-generic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1959041 Title: STR (suspend-to-RAM) freezes at suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1959041/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
