This type of crash results when a kernel routine invokes a trapinstruction.
这种类型的中断是由内核例程调用了trap指令引起的。

You set some registers and issue a system call instruction (or an interrupt) and have the kernel code called directly from the trap handler.
你可以设置一些寄存器，并发出一个系统调用指令(或中断)，并由陷阱处理程序直接调用内核代码。

Important registers to look for when debugging through signals are the GPRs, instruction pointer (NIP), machine state register (MSR), trap, data address register (DAR), and so on.
