OSX Snow Leopard "System uptimes in nanoseconds"

[macosxlover]

Hi,

I have got the leohazard release of Snow Leopard 10.6.1-10.6.2. Straight after I install I get a kernel panic, saying "System Uptime in nanoseconds = 3456745". Is there any fix for this and if not please point me in the right direction for snow leopard. My specs are below

AMD Ahtlon X2 4200+
Asrock alivexfire esata2 motherboard
2gb DDR2 800
Nvidia Geforce 9500GT 512MB
160GB Sata HDD

Thanks to you all!
