-x32 bit m8, seems like the only solution so far. I've been in 32bit + 30 mins without panics so...

I think its mobo related as some will need more kexts to run. I've got a feeling my GA-P35-DS3P needs proper kexts for 64bit.

I wonder if I should do another install from within SL, I highly doubt it will fix the panics though?
