Finally, I gave up and reverted to vm/uma_core.c,v 1.114, this game me a working savecore. Unfortunately, either kdgb(1) doesn't work on sparc64 at the moment, or this core is troublesome -- it would endlessly print this: kgdb: kvm_read: invalid address (203d2025) kgdb: kvm_read: invalid address (6e666f20) kgdb: kvm_read: invalid address (203d2025) kgdb: kvm_read: invalid address (6e666f20) kgdb: kvm_read: invalid address (203d2025) kgdb: kvm_read: invalid address (6e666f20) kgdb: kvm_read: invalid address (203d2025) kgdb: kvm_read: invalid address (6e666f20) =2E.. At least I can confirm that reverting to rev. 1.114 fixes a problem.
