I've been trying to get some kind of kernel messages from it but I can't get any debug IO done successfully. It has hung on me 3 times in a row today. I'm using this command: fsx-linux -l 100M -N 50000 -S 0 fsxtestfile This is run in a new partition on a IDE drive (/dev/hda7, using legacy IDE drivers). Any suggestions for debug output? I can see SysRq output on-screen (sometimes) but it doesn't make it to my serial console. Any patches to test? :) Thanks, --- ~Randy
