[full quote for the benefit on Andy]
I don't want to blacklist all of Nvidia for a single report. Greg,Andrew, please don't apply these patches for now.
We have lots of systems with NForce4 chipsets and >4GB and so far nobody has reported such an issue. In fact it works fine for me on such a system. So something must be very specificially wrong on your system.
Andy, do you have some thoughts on this issue? Could it be a BIOS that programs something wrong?
The server systems with NF4-Prof seem to certainly work.
