I know how to find a panic file on my M1 but not what to do next.
panic(cpu 1 caller 0xfffffe0014092de0): "AppleHSBluetoothDevice::setPowerState(0xfffffe2336859240 : 0xfffffe00159f3e1c, 1 -> 0) timed out after 10301 ms" Debugger message: panic Memory ID: 0x6 OS release type: User OS version: 20C69 Kernel version: Darwin Kernel Version 20.2.0: Wed Dec 2 20:40:21 PST 2020; root:xnu-7195.60.75~1/RELEASE_ARM64_T8101 Fileset Kernelcache UUID: 3E6AA74DF723BCB886499A5AAB34FA34 Kernel UUID: 48F71DB3-6C91-3E62-9576-3A1DCEF2B536 iBoot version: iBoot-6723.61.3 secure boot?: YES Paniclog version: 13 KernelCache slide: 0x000000000bd90000 KernelCache base: 0xfffffe0012d94000 Kernel slide: 0x000000000c8d0000 Kernel text base: 0xfffffe00138d4000 Kernel text exec base: 0xfffffe001399c000 mach_absolute_time: 0xe0183cb78 Epoch Time: sec usec Boot : 0x601561fe 0x000646fa Sleep : 0x60161cb9 0x00040e51 Wake : 0x60162195 0x0001e857 Calendar: 0x601621a4 0x0007e7fc

What is the possible reason of the crash ?
Best Answer
These are hard to debug specifically, but if you want to, set up the Mac to save the core dump file (or send them to a network server that collects cores) and use a second Mac to inspect the call trace.
The second link covers how to get the KDK which is the kit that helps debug and log more details. You have a report, but it’s likely there’s not enough detail to trace back what actually happened. Everyone can see the debris from an accident, but all the evidence wasn’t collected by default. The KDK sets up a forensic situation where you could definitively answer what happened after the fact.
On Intel, the nature of a panic is the same at a high level, but very different in the specifics for your Apple Silicon based mini with an M1 CPU. Here is an archived article from Intel days that explains the basics very well. Forgive the kitchen metaphor if you’re well read on machine language faults already or the idea of kernel space crashes.
The core is not in a logical state to continue, basically. Why did this happen? Odds are it’s hardware putting a value in the software didn’t ever expect to see. Like if you told the code to expect one to three fruits as input to make a smoothie and instead a dead rat showed up to be processed. The kitchen shuts down to figure out what the heck is going on rather than make a dead rat smoothie as previously instructed from one to three fruits.
So, Apple might make code to say, dispose of dead rodents and then wait for more fruits to make smoothies. Then the next time, a “dead rat exception” would be handled until say 4 fruits show up. Then more handlers need to be written or the kernel changed yet again...
