After installing the new Vista Client I get this bluescreen (Vista64):

Address fffffa6008a0eccd
base at fffffa6008a00
datestamp 48bef9740

The OS is booting fine. Login successfully completes. 3 - 5 seconds
later the bluescreen happens. It doesn't matter, if I just sit and wait
or if I start some EXE, within 5 seconds -> [BLUE]

Regards, Rudi.
