How about a hard power switch? + crash report
#1
Bug 
Debian + MATE MrFixit version 2.0
Kernel: Linux Debian-Desktop 4.4.213 #1 SMP Fri Feb 7 13:03:55 EST 2020 aarch64 GNU/Linux

While playing an mp3 with mplayer through the internal speakers, I had the system freeze so hard that I had to take the back cover off & push the reset switch to get it to reboot.
For the next incremental hardware tweak, how about adding a hard power switch in a more accessible location?

The last thing it wrote to the logs:
Code:

IIRC it was actually still running after that. The next time I tried to play the mp3, it froze. There was soft static coming from the speakers.


And then when I tried to post this, the PBP rebooted. That didn't leave any message in the logs [edit] but there's a console-ramoops-0 and dmesg-ramoops-0 in /sys/fs/pstore that look like they're from the right time.

Code:
<1>[ 1352.655030] Unable to handle kernel NULL pointer dereference at virtual address 00000000
