What does "Process adsmcli" do? Does it make any special system-calls
or does in interface with a particular driver? Whatever it's doing
may have triggered the event.

This code is not valid. Either some hardware burped or a pointer to
a function got corrupted, both quite likely RAM related.

The "Re: Kernel Bug at spinlock.h ?!" is an eye-catcher because this
inline code cannot have any bugs or you wouldn't even have booted.
