Created attachment 1477516 [details] Full log of systemctl suspend on trimslice Description of problem: When trying to enter suspend on tegra20 (Trimslice), I'm experiencing a crash related to the pxa_gpio driver that seems registered and prevent entering suspend. Version-Release number of selected component (if applicable): Current fedora branches. Reproduced on kernel 4.18.1 How reproducible: always (at least on a tegra20) Steps to Reproduce: 1. boot using a serial with initcall_debug and no_console_suspend=1 2. log on serial from another host (there is no journal output of theses) 3. systemctl suspend Actual results: [...] [ 118.291482] Disabling non-boot CPUs ...

(here pxa_gpio_suspend) Additional info: pxa_gpio is selected by CONFIG_ARCH_MMP and CONFIG_PLAT_PXA. I'm suggesting to disable theses arches and any dependencies until a proper fix is made upstream. (patch to be sent soon against the fedora kernel config).
