How do I fix this? Go into the BIOS setup and disable the boot virus protection. + + + + My system has more than 1 GB of RAM, and I'm getting panics + with kmem_map too small messages. What is + wrong? + + + + Normally, FreeBSD determines a number of kernel parameters, + such as the maximum number of open files that can be opened + concurrently, from the amount of memory installed in the + system. On systems with one gigabyte of RAM or more, this + auto-sizing mechanism may choose values that are + too large, leading to poor performance, or even to + panics. + In this particular case, the kernel memory allocation map + is too small for the amount of memory the kernel believes it + should be able to allocate, hence the panic. Compile your own + kernel, and add the to your + kernel configuration file.
