I don't run X myself. Unfortunatly, it only hangs when you are within an xterm and looking at the display. E.g. you can run sleep 60; dd if=/dev/mem... switch to a vty and wait, and it will work just fine. If you are looking at the display, it just hangs and you never get a dump, or the chance to switch back to the debugger. -- Mike Pritchard mpp@minn.net "Go that way. Really fast.
