  "segmentaion" error when DMAing

Status in QEMU:
  Fix Released

Bug description:
  When working with QEMU's PCI network card E1000 emulator, I
  accidentally put virtual addresses into the memory mapped registers
  when I should have put physical addresses. Short story is, the address
  was too large for the physical address space so when the network card
  tried to DMA the location it tossed a "segmentaion" error out to the
  console. That's right--not a "segmentation" error, but a "segmentaion"
  error. I just thought I'd let ya'll know about that little typo.

  My "qemu -version" gives "QEMU emulator version 0.15.0, Copyright (c)
  2003-2008 Fabrice Bellard" on linux version 2.6.32. I guess it might
  be an older version, dunno if the typo's still there.
