10.6.8 or 10.7 reboot loop (P35-DS4 GTX275)

[irri]

I'm running 10.6.7 fine, but if I try to update to 10.6.8 or to install 10.7, I get the same problem. The computer gets as far as "mig_table_max_displ = 72" then instantly reboots. Is there any problem that would happen with both 10.6.8 and 10.7 which could cause this?

 

I've tried all sorts of boot switches and adding the NVEnabler, but nothing seems to work.

 

Thanks in advance.

in dsdt

 

PCI0 needs _UID, 0x00 and _ADR, 0x00

 

what is in /Extra/smbios.plist

model ?

 

boot with

-v UseKernelCache=No npci=0x2000

Thanks for the help.

 

The boot switches didn't help. I'm not sure how to modify dsdt. The patcher doesn't seem to have options.

Thanks a lot, but I solved the problem...

 

I was on bios F11. An update to F14 fixed everything.
