Cause

A driver overran a stack-based buffer (or local variable) in a way that would have overwritten the function's return address and jumped back to an arbitrary address when the function returned.

This is the classic "buffer overrun" hacking attack. The system has been brought down to prevent a malicious user from gaining complete control of it.

Resolution

Use the kb (Display Stack Backtrace) command to get a stack trace.

The last routine on the stack before the buffer overrun handlers and bug check call is the one that overran its local variable.
