Recently, I frequently observe similar stalls on Mac mini G4 (UP).

I can work around the problem by this patch:

https://gist.github.com/rokuyama/53898de1e9ff67b86ac8e53f552dc582

With this patch, general pool allocator is used for struct pmap,
instead of pmap_pool_allocator(), which is intended for PVO
entries below 256MB.

Thanks,
rin
