There’s still something wrong with this. I have a machine with 28 cores (56 with hyperthreading) and 256GB of RAM, and ever since you committed r281162, it panics early in boot with a failed assertion. It looks like the first few members of a uma_slab_t are getting overwritten accidentally, and somehow the padding of the extra member in the uma_zone_t was previously protecting it. I don’t know the exact cause yet, but I must ask that you revert to r281161 in HEAD and stable/10 until the problem is resolved.
