You are running out of VM space in the kernel. You have two choices.
* figure out how to rearrange memory mappings for the CATS to allow
KERNEL_VM_SIZE to be bigger.
* Change PMAP_STATIC_L1S in your kernel config to a smaller value (or reduce
If the comment in vmparam.h is to be believed there is no reason why
KERNEL_VM_SIZE could not be increased on the CATS anyway. There are some
patches which resolve the issue for the Risc PC/A7000 in PR12119.
