I was running a stress test (stress -c 4) and measuring the temperature and cpu clock frequency. I also edited the config.txt to overclock my Raspberry Pi 3B. I entered sudo reboot into the terminal and it was rebooting, but then it got stuck on the following screen:

Raspberry Pi stuck on this screen

What could be the cause of this error? How can I appropriately reboot my Raspberry Pi?

EDIT: After shutdown in accordance with @E_Angel's answer, I got a new error:

To appropriately reboot pi(Linux ) you can use combination key similar to windows , but made for linux :


alt + print screen + O


alt + print screen + B

Sync discs

alt + print screen + S
  • Thanks, but what about the error above? will it fix that?

  • Are you not yet able to properly reboot with combination keys ?

  • Lol it's worse. The Raspberry Pi gave the following error when I shutdown and started up the Raspberry Pi again: "unable to handle kernel paging request at virtual address 17e6e00e"

  • Googling gave some similar situations but with different addresses . Do you have some media attached to usb ?!

The problem was resolved by editing the config.txt file to undo the overclocking. In particular the arm_freq was changed to its original value of 700 MHz. I will ask another question on whether or not this means my RPi3B is not overclockable.


in boot/config.txt string hdmi_force_hotplug=1 change on #hdmi_force_hotplug=1
