Can't say for sure ACPI broke the instant I upgraded to RELENG_6 but it was running RELENG_6 that I found only 1G listed at the top of dmesg. Only thought to look at that part of dmesg when the machine started swapping unexpectedly. Started searching how to control or hint to the kernel my true memory size and found hw.physmem and that /boot/defaults/loader.conf listed it at 1G, same as my system was running. Can't say for sure whether it was commented out in defaults but assumed I was being told it was being set to 1G there or somewhere as the system default. Something has changed as the 6.0-RELEASE CDROM got my memory size correct, and recent RELENG_6's get it correct, both without assistance from hw.physmem. -- David Kelly N4HHE, dkelly@HiWAAY.net ======================================================================== Whom computers would destroy, they must first drive mad.
