I will try "clamping" the memory in machdep.c next... Yes. This is going to be necessary; we see here: > real memory = 9126805504 (8704 MB) > avail memory = 8613085184 (8214 MB) that it's seeing all the memory. It has to base it's calculations on the amount of real memory available for use in wired pages for KVA. Jake could better tell you how much KVA/UVA is lost to the bank selection overhead; a good guesstimate (IMO) would be to use the value of "3G" for the calculations for all the kernel allocations that the "automatic" of "MAXUSERS=0" selects. You may also want to just try (as a quick-and-dirty hack) setting "MAXUSERS=256" or something similar, and see if it gets you to an initial (badly tuned) boot. -- Terry
