Much more helpful than any of these things would be a description of what the test _does_. Seeing a stack trace after the problem has occurred isn't much help for tracking down what events caused the problem; to do that we need to know what was happening before the problem occurred. There are two relatively easy things you could do that might also help a little: Decode the addresses in the stack dump into source line numbers (probably requires that the kernel be built with debugging information). Make the console output document in pastebin.com include the _complete_ console output, not just the part starting from when the problem was detected. Alan Stern
