Just searched the mailing list archives and it's suggested to add
in:
options VM_KMEM_SIZE_MAX=(768*1048576)
options VM_KMEM_SIZE_SCALE=2
to the kernel config file to fix this. Is this eventually going to be
fixed? I looked at the coverstation between Terry Lambert and David but
I'm still not sure what the number in VM_KMEM_SIZE_SCALE represents since
I know it defaults at 3 but is the 3 like the VM_KMEM_SIZE_MAX divided by
3 or how does it work?
