I do not have another dev kit.
I think it might have something to do with display. The display port was connected to a VGA adapter to work with my old monitor.
I used this script I found from another post:
test_period=4
for i in {1..500}
do
echo "Iteration: $i"
sudo /usr/sbin/rtcwake -m no -s $test_period
sudo systemctl suspend
sleep $test_period
done
[display-cause-kernel-panic-during-suspend] (Display cause kernel panic during suspend)
Using that script caused a kernel panic:
minicom_vga_adapter.txt (82.1 KB)
I am using a newer monitor which has a display port and ran the same script which did not seem to result in a kernel panic:
minicom_dp_to_dp.txt (12.0 KB)
I am going to keep using this new monitor and will give an update on whether the problem persists.
