I wish, I could give you some clear and immediate solution, but again, we're dealing with one BSOD indicating one file, udfs.sys (UDF File System Driver)
Actually, error in the above file, seems to be connected to you using an optical drive (CD\DVD drive).
It may be just a single, meaningless event.
Remember, BSODs happen.
Is your Vista up to date?
Let's see, if your system files are Ok...
Go Start>Run ("Start Search" in Vista/7), type in:
Click OK (hold CTRL, and SHIFT, hit Enter in Vista/7).
Have Windows CD/DVD handy (with Vista/7, most likely, you won't need it).
If System File Checker (sfc) will find any errors, it may ask you for the CD/DVD (rarely in Vista/7 case).
