Thanks. This tells you that you're tracing back through a system call. The offset you show below isn't related; it's a long way before the system call address. > Jul 7 00:33:07 cfxu /kernel: instruction pointer = 0x8:0xc01b6e8f > ^^^^^^^^^^ What you really need to do now is: 1. Build a kernel with debugging symbols. Only bde can analyse a dump without them. 2. Enable processor dumps. 3. Read the chapter in the handbook entitled "Kernel Debugging". When you've done that, come back and I can take another look at what's happening. In particular we need to know what the traceback looks like.
