Apple’s M1 processor and the full 128-bit integer product

I haven't noticed poor wake times, but my laptop does kernel panic and reboot a fair amount. Maybe 4 times in the past week. My hunch is that it's Spotify's fault but I haven't dug into the logs.

A user-land program cannot be at fault for a kernel panic, that is the kernels fault, always.

xnu will panic if it doesn't receive periodic check-ins from userspace. For example if WindowServer hangs, then the kernel may deliberately panic so that the system reboots. See man watchdogd for (a tiny bit) more.

True, but a third-party program shouldn’t really be able to do this, at least not easily.

I have this problem but only if I've been plugged into a monitor, and then unplugged and gone onto battery. Rebooting after unplugging stops it but its annoying.

I've had mine panic and reboot twice, both times happened shortly after disconnecting other Macs that were connected via a Thunderbolt cable (target disk mode).

How does spotify panic the kernel itself?
