I can reliably trigger this by a simple `tar xf /var/db/portsnap/.tgz` as root. I'm taking r262372 for a spin now (Which of course includes your r261983), and have been able to successfully extract the ports tree as root without being dumped into ddb. Though... I have been sitting here waiting for the snapshot verification for quite a while, but that's another story. The only thing untoward I see is that UFS lock order reversal... lock order reversal: 1st 0xc2f73394 ufs (ufs) @ /usr/src/sys/kern/vfs_subr.c:2101 2nd 0xcd25c3c8 bufwait (bufwait) @ /usr/src/sys/ufs/ffs/ffs_vnops.c:262 3rd 0xc2f93934 ufs (ufs) @ /usr/src/sys/kern/vfs_subr.c:2101 ... but I think that's well known at this point and isn't a cause for my concern. Thanks Ian!
