Observed on two host systems both with openSUSE 11.3 32 bit using ext4:

When a big files, in this case a 1.2 GB and a 1.7 GB is copied from DVD, usb harddrive or shared folder into a Windows 7 32 bit guest system, the copied file is corrupted. The md5sum has changed and until the guest system has been rebooted successive md5sum tests on the same file comes up with various results...
After a reboot md5sum tests show consistent results, but a sum different from the original file.

Can anybody confirm this??
