Hi Mike. Yah, this problem just came to light recently. There is a fix in the works which I hope to get into the upcoming 4.4 release. In the mean time the easiest thing for you to do is to drop the box down to 3G. Basically the problem is that the swap subsystem is trying to reserve way, way, way too much kernel virtual memory. It calculates a number relative to the amount of ram in the machine and that calculation is broken. Once you get the machine up, if you know how to compile up kernels, I can provide you with a patch that should get the machine working with 4G. If you don't know how to compile up kernels the best thing to do is to just leave it w/ 3G in until the 4.4 release (which will be at the end of this month / early next month). -Matt : :I am trying to install FreeBSD 4.3-RELEASE on a machine :with 4GB of memory. The motherboard is a SuperMicro 370DL3 :with a ServerWorks chipset. : :The installation kernel makes it almost all the way through :the boot sequence, to the point (I think) of running the :first user level process /stand/sysinstall. The last normal :output before the crash is: : : /stand/sysinstall running as init on vty0 : :it immediately panics before sysinstall gets a chance to :put up its colorful screen: : : panic: swap_pager_swap_init: swap_zone == NULL : :The system works fine if I cut the memory down to 3GB. : :So, questions: : :1. Is 4GB supposed to work in 4.3? Does it work with other boards? : :2. Any suggestions on fixing this so it works?
