Opteron problens with 16GB memory

[Martin Nilsson]

Are there any known problems with Opterons and more than 12GB memory?

I'm running 5.4-STABLE on a Tyan K8WE, the box is stable with 12GB
but I get internal compiler errors when building world with 16GB.

Disks are on a MegaRAID 320-2e kontroller (PCI-express) could there
be something wrong in the amr driver when having lots of memory.

I remember having similar problems on a MSI board with lots of memory 
a couple of months ago.
