[SOLVED] System does not poweroff or reboot

Trying Arch on an old laptop Dell Inspiron 1501. After installation I found I cannot power off the laptop. When I type "poweroff", it turns off everything but the power LED is still on. I have to press the power button 5 secs to fully shut it down. If I type "reboot" it hangs at the same place. Everything seems to be down but the power LED is still on and it does not restart the laptop.

I tried removing "quite" from grub so that it can print out more info. I see it prints "Reached target shutdown" and then turns off the screen. Everything seems to be down expect the power LED. Since the fan is not on I cannot tell if the CPU is still on.

I notice if I boot Arch from USB there is no such an issue. I can use "poweroff" to turn it off completely.

I've tried both the default kernel and the LTS kernel but got the same problem. Checked journalctl output and noticed some warnings regarding wifi card driver and video card driver (radeon). I disabled these modules and then tried poweroff but still the same.

Question: How can I find what is doing differently between boot from USB and boot from hard drive after installation? I think if I can find the difference I can try the same. If there is something else I can try to narrow down the issue please let me know as well.

Not sure if it matters but there is the system spec:

Inspiron 1501
AMD Turion 64 X2 Dual-Core Mobile Technology TL-50
ATI RADEON® Xpress1150
2GB RAM

Re: [SOLVED] System does not poweroff or reboot

@loqs, Thank you for the pointer. So is this a bug in the kernel? It's weird I have tried the latest LTS kernel (version 4.*) and saw the same issue.

Ah, I see. Thank you for the info. It seems when boot from USB the kernel is 5.3.1 so it makes senses it does not show this problem. I will give previous kernel a try then.

Tried 5.3.4 kernel and it worked. Thank you for the help.
