Unforch, when /dev/nst0 has reported an error during the amcheck cycle, on 2 of the 4 tapes that it read just fine yesterday, and then I do a rewind on one of them, and issue a 'dd if=/dev/nst0 count=1' which *should* spit out the tape header onscreen, what I'm actually getting is that nothing touches the drive as far as moving the tape or changing the "Ready 1" display on the face of the changer, but I do have a hung dd that can only be gotten rid of by a reboot. It cannot be killed, not even with a -9. I do not know if this is a new development in kernel history or not, but it sure is a PITA. Its been hung for about 20 minutes now. Is there anything that I as a big dummy can do to remedy this? -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
