incase anyone cares, or has the same problem, it was a single BIOS setting that had me rebooting constantly.
details can be found here, thanks to DUNE31! #96
WELL I WANT TO SUMMARIZE THINGS:
BIOS SETTINGS ARE VERY IMPORTANT ! SO THIS IS A BIOS SETTING TEMPLATE :
To your CPU CONFIGURATION section :
MAX CPUID VALUE Limit (or similar) : Disabled
Vanderpool or virtualization : Disabled
CPU TM Function : Enabled
Excecute Disable Bit (or called NX or XD on some mobos) : Enabled (the most important, if not enabled the result is reboot loop with vanilla kernel)
To your POWER section :
ACPI 2.0 Support : Enabled
ACPI APIC : Enabled
I had the "execute disable bit" to disabled, though in the asrock bios is was called something else. as soon as i changed it, whammo, no more constant rebooting after seeing a quick flash of the EFI text.
the new install on a sata drive, from a sata DVD, GUID, vanilla.
OS sees the drives (250 and 500 gig) no problems, no apparent speed issues, no compatability mode enabled, afaik.
