The system is currently running a kernel from a similar machine with the same settings. The machine does run on this kernel: 4.9-RELEASE FreeBSD 4.9-RELEASE #8, with the above options, but I have not been able to compile a 4.9-RELEASE #2 (which is the source tree on the machine) kernel that has an identical config file. So, when it builds itself from -RELEASE sources, it hangs at: "pmap_mapdev: Couldn't alloc kernel virtual memory" I couldn't find a reference to anything recent. Nothing non-default (from a GENERIC kernel) with respect to ACPI has been touched. I see a reference to -CURRENT from 9/03, but that's it. Should I turn off power management? Is there a way to prevent ACPI support from being loaded at the kernel level? Should I just cvsup to 4.9-RELENG and try it again? It would be very nice if this were some how related to my network performance problem, but that might be too much to hope for. :) Thanks in advance, DJ
