Grr. I built a kernel with WITNESS and INVARIANTS, and though I get some (previously-reported, and apparently harmless) LORs on boot, I can no longer reproduce the gmirror failure or the panic. (The i/o scheduler is not too shabby, either, as I'm seeing something like 20MB/s on each disk with four parallel bonnie++ processes.) So ... a race condition, then? -Ben Kaduk
