The problem here is that on some IPF machines (typically the HP rx2600) the physical memory layout is sparse. It's this sparseness that's causing problems, because currently we allocate a vm_page array that needs to be physically contiguous. When a machine has only 2BG of memory, but 1GB is located above the 4G boundary, we need a vm_page array that can be larger than the size of any of the usable memory regions. Not to mention that the vm_page will represent pages (roughly 3GB worth of it) for memory that isn't even there. A fix for this is in the pipeline. All it takes is time. If the memory layout for the machine is not sparse, you can take out the code from sys/ia64/ia64/machdep.c that skips memory above 4G. Beware of DMA problems caused by the need for bounce buffers when you do that... -- Marcel Moolenaar USPA: A-39004 [EMAIL PROTECTED] Thanks for the responses. I tried to comment out those lines from sys/ia64/ia64/machdep.c and successfully rebuilt the kernel. Upon reboot, it detects the 8G of ram (wonderful!) but reports only the 4G as available, then it freezes while loading FPSWA. Well, I think I'm gonna wait for some time until you guys will fix it (hope so soon).
