DeletedUser856 I am not an expert. Below is what I think I see.
All of the crash dumps include "Watchdog or Long Press Power Key Detected" and don't have panic information from any core. This suggests that either the power button was held down for a long time, or some of the CPU cores got stuck.
Most of the dumps show no lockup warning, but b62fd705d046 shows "Hard Hang" for core 0 and "Lockup Warning" for most of the rest of the cores.
The most obvious guess is a hardware problem, and the fact that the one dump shows different a different lockup diagnosis than the other ones modestly increases the likelihood of a hardware problem. Less likely, but possible, would be if some particular application or particular load were leading to a hardware lockup, e.g., causing the GPU to run amok.
DeletedUser856 Does anyone know how to fix this?
If it's a hardware problem, replacing the device would probably be much less expensive than repairing it.
Note that support is expected to end for the Pixel 6 on October 1 (source). The project recommends Pixel 8 or newer (source). Edit: oops, somehow I "decided" the report was from a 6 rather than an 8.
