Hi,

I'm doing some experiments with the patches from
http://people.brandeis.edu/~jcoiner/qemu_idedma/qemu_dma_patch.html
I'm running QEMU on linux, so using only the first to
patches (qemu_dma_patch.tar.gz and qemu_concurrent_io.patch)
works.

Problem: Starting QEMU with the option "-snapshot" produces
the following error message:

  qemu: /usr/src/packages/BUILD/qemu-snapshot-2005-10-03_23/block.c:424: 
bdrv_cancel_nonblock_io: Assertion `nbst->state == STATE_READ_DONE' failed.
  Aborted

It doesn't matter if I use Win2000, WinXP or Linux as guest.

Am I doing something wrong? Everything seems OK when omitting "-snapshot"
from the command line.

Thanks for help,
Uli
