If I build attached kmod and kldload/-unload it on a GENERIC kernel w/
SMP & apic it'll error out:
"Zone was not empty (xx items). Lost X pages of memory."
w/o SMP & apic the problem disappears.
This is on a p4 HTT, but seems reproducible on "proper" SMP systems as
well. UP systems don't show it however.
Can somebody please try and report? Thanks!
