Part Number: AM5728
Tool/software: Linux
Hi,
With SDK 06.00.00 - non-RT Linux Kernel I have the behavior that my device is not turning off/rebooting roughly every 3 try. (Doesn't matter if I use "reboot" or "poweroff")
[ 26.296779] systemd-shutdown[1]: All filesystems unmounted. [ 26.302658] systemd-shutdown[1]: Deactivating swaps. [ 26.307998] systemd-shutdown[1]: All swaps deactivated. [ 26.313510] systemd-shutdown[1]: Detaching loop devices. [ 26.322826] systemd-shutdown[1]: All loop devices detached. [ 26.328730] systemd-shutdown[1]: Detaching DM devices.
It's just stopping after this messages and does not reboot neither turn of the PMIC.
I observed this before with the 4.14 Kernel. See thread here: https://e2e.ti.com/support/processors/f/791/p/707480/2611704#2611704
The issue was fixed by "Keerthy J " by reverting the commit "0d5e04e sched/core: Require cpu_active() in select_task_rq(), for user tasks". Which also made it to the SDK last year.
With the switch to the 4.19 Kernel the commit is not reverted any more. But even with reverting it myself I still experience the issue. So it is kind of different.
I'm currently testing with our own HW (which design is pretty close to the IDK). If I find the time I'll dig out the am5728 IDK and see if I can produce it there too.
Regards,
Michael
