  Hi all,

  I purchased an old-stock but new HP 5100C at a good price because I thought it
  was well supported under Linux (according to the research I did). But I've hit
  some unexpected problems. I think the problems reside in the ppscsi and epst
  modules. However the expertise of the sane developers might help me to
  understand what is going on.

  Firstly the ppscsi/epst modules appear to have SMP issues with my Abit BP6. I
  receive CPU lockups and am no longer able to use the scanner unless I reboot
  (and even though the computer continues running a reboot/shutdown won't
  complete and a hard reset is necessary). I am now running uni-processor to try
  and isolate the other problems.

  Using scanimage I can only copy black and white.
  These are the error messages I receive when trying scanimage with the "--mode
  Color" option (or gray option):

  epst.1: Command abort not supported
  epst.1: Bus reset

  The big difference is that I am still able to use the scanner after this
  happens compared to when I am in SMP mode.

  Has anyone else seen these "Command abort" messages when trying to copy in
  colour/grey with the epst module an an HP5100C?

  I am running 2.4.2 with the 2.4.x ppscsi and epst modules.

  Thanks,
  Adam
