M1 Air keeps crashing

I wonder if its an m1 thing or if the intel ones had this issue too

The Intel one (2018/2020) was notorious for T2 chip related kernel panics. I had mine replaced 5 times by Apple. Eventually Big Sur came out and that fixed the issues.

Also what is DART. I know what UART, which is modem hardware:

Address Translation on 64-Bit System Architectures​

Apple solved the problem with address translation which “maps” blocks of memory into the 32-bit address space of a PCI device. In this scheme, the PCI device still sees a 4-gigabyte space, but that space can be made up of noncontiguous blocks of memory. A part of the memory controller called the DART(device address resolution table) translates between the PCI address space and the much larger main memory address space. The DART handles this by keeping a table of translations to use when mapping between the physical addresses the processor sees and the addresses the PCI device sees (called I/O addresses).

Ok, after quick glance, my impression is, that it is part of the memory controller, translating to 32bit PCI address space to 64bit Memory space.

Thanks for the link, I learned something new . I will hardly need the details, since I have no plans to develop PCI drivers, but it is good to know, when trying to make sense of crash/panic-logs
