A method for performing kernel-level diagnostics. The method includes obtaining a hardware trap associated with an attempt by a kernel-level instruction stream to access a memory address, wherein the memory address is referenced by a hardware watchpoint facility, forwarding the hardware trap to a software breakpoint handler, executing a diagnostic instruction defined by the software breakpoint handler to obtain diagnostic data, transmitting the diagnostic data to a user, and returning execution flow to the kernel-level instruction stream.
