Kernel Panic on 10.6.2 Install !!!!!

[hackmac]

Tried OS X Snow Leopard 10.6.2 Patched DVD for Intel-AMD by Hazard... It installed fine, used 'Legacy Kernel' but after installation while OS X boots up I get "Debugger called <double panic>" message after loading Apple HDA & TMCey driver or something like that I'm not exactly sure....

But when I reboot the machine I get a CMOS checksum error after the POST !!!!!!

Any suggestions ????

2GB 667MHz DDR2 (Transcend)

Snow leopard can have different effect to all people's BIOS, so I'm not sure about the checksum error.

Please could you post an image of this KP? You haven't given us much info here.

You could try booting up with -s and when it's loaded, if the problem is affiliated with AppleHDA
mount -uw /
rm -Rf /System/Library/Extensions/AppleHDA.kext
exit
and then see if the machine boots.

Thanks for all your help ...

The CMOS bug gets solved after installing Legacy AppleRTC.kext and no kernel panic on legacy kernel .....
