New Revision: 230630
URL: http://svn.freebsd.org/changeset/base/230630
Log:
For machines where the kernel address space is unrestricted increase
VM_KMEM_SIZE_SCALE to 2, awaiting more insight from alc at . As it turns
out, the VM apparently has problems with machines that have large holes
in the physical address space, causing the kmem_suballoc() call in
kmeminit() to fail with a VM_KMEM_SIZE_SCALE of 1. Using a value of 2
allows these, namely Blade 1500 with 2GB of RAM, to boot.
