One would think it has a recent kernel (I neglected to look while it was running to find out what kernel it was). so I ran a bunch of commands to copy stuff to and from it, and while it took a few minutes, it also failed in more or less the same way. I'd guess that means that whatever the bug is, it's not fixed in Linux, yet. :( :( :( -- ---- Fred Smith -- fredex at fcshome.stoneham.ma.us ----------------------------- "Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but only he who does the will of my Father who is in heaven." ------------------------------ Matthew 7:21 (niv) -----------------------------
