Description of problem:
  I have a WinXP VM running on a box running F12. 90%+ of the time, when I try
to make a copy of the virtual disk image (for backup or restore), the host
gets a kernel panic reporting "BUG: scheduling while atomic mount.ntfs/1040/0x10000102.

Version-Release number of selected component (if applicable):
  2.6.32.12-115.fc12.x86_64

How reproducible:
  Copy a large file between an ext and ntfs file system


Steps to Reproduce:
1. Stop virtual machine (kill qemu process or shut down VM)
2. Stop libvirtd
3. Attempt to copy file via cp or dd
  
Actual results:
  Kernel panic & backtrace
