Comment 12 Gal Hammer 2012-12-20 09:53:54 UTC 
I'm unable to reproduce it with version virtio-win-prewhql-0.1-49. There was a fix to a similar scenario (guest->host and not host->guest like this bug) that might solved this bug as well.

Mike, can you please test it again to confirm? Thanks.

on build49 ,Bug 882795 blocks me to verify this bug.
on Build 51 ,I did not hit this issue ,only find an new bug that is virtio-serial driver does not work after s3/s4,referring to Bug 902153.

Based on above ,this bug can be considered fixed ,

Move Status to Verified.
