Why is panicing in the kernel on an error not an option? Like kernels can write a core dump and reboot, right?

I guess when the kernel panics, there is nothing to write the core dump for you...

The kernel crash dump mechanism works by reserving some memory, which it boots a fresh copy of the kernel into on kernel panics, which then takes care of reading the old dead kernel from memory and saving the dump.

Of course this working requires the fresh kernel to be able to get up and do that without itself crashing, so it can't capture every scenario. And it is bringing down the system completely, and there's lots of pros and cons to be argued about that vs attempting to continue or limp along.
