Kernel panics (assumed to panic due to non-responsiveness and blinking caps-lock) upon wakeup from suspend-to-RAM Known good (non-panicking) kernel(s): hardened-sources-4.1.7-r1 Known bad (panicking) kernel(s): hardened-sources-4.4.6 hardened-sources-4.3.3-r4 The kernel .config changed between 4.1.7-r1 and 4.4.6. 4.3.3-r4 used the 4.4.6 .config backported with "make silentoldconfig". I am led to believe the likely sources are: a regression in the kernel, a regression in the hardened patchset, and/or a bug or regression dependent upon a particular .config to manifest. I'm currently backporting the 4.4.6 .config to 4.1.7-r1 to test the last possibility. ...I assume a kernel panic counts as a crash or hang which is why I'm initially marking it as Critical. Reproducible: Always Steps to Reproduce: 1. Suspend to RAM (tested with "systemctl suspend" from console and multiple Desktop Environments and the native suspend mechanisms of multiple Desktop Environments; auto-suspend not tested) 2. initiate wakeup (tested using keyboard events) Actual Results: nön-responsiv box und blinkenlichten früm die kapslök Expected Results: Die boxen tu wäkup und displäyen die skreenlökker ur die DispläyenManagur

While my profile is hardened/linux/amd64/selinux, the systemd blockers are overridden. 4.4.6 was tested with multiple versions of systemd tested with/without OpenRC installed (systemd used as init throughout) and with/without laptop-mode-tools installed: no change. 4.4.6 was also tested by suspending from both a sysadm_r and non-fully TPE restricted account and a user_r and fully TPE restricted account: no change.
Did you test against vanilla-sources with comparable .config's?
It's the likely the .config: 4.1.7-r1 gets the panic with the backported 4.4.6 .config. @Anthony Basile: Not yet, I'll try gentoo-sources also.
