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:
[...]

Expected results:
There should be no initcall related to hw others than tegra.
(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).
