A bit of context:
I recently modified my pi400 by disconnecting the d+ and d- that connect the on-board keyboard to the usb processor IC. I then connected those pins from the usb processor to the usb output of a mechanical keyboard in an attempt to have a mechanical keyboard permanently attached without sacrificing a usb port.
Everything runs fine until I try to shutdown the pi when one of two things happens:
1- the system turns off but then immediately reboots
2- the system begins to shut off but then gets prints lots of info about rcu stalls and then gets stuck in the following loop;Can’t seem to find any of the messages about rcu or the shutdown messages in any of the logs, so a point in the right direction would be appreciated.
I’ve tried using the pi with a fresh OS image and the same thing happens, so I’m fairly certain it’s a hardware issue related to my tinkering.
Thanks in advance for taking the time to read this and interact!
