Nothing I did fixed it. Eventually, after wiping the disk, I tried a clean install, having concluded that it might be a hardware problem. It booted. Curious. Then it hit me: gpart backup ada0 | gpart restore -F ada1 gpart bootcode -b /boot/pmbr -p /boot/gptboot -i 1 ada1 actually *is* the problem. I ended up manually repartitioning the disk with gpart create then manually creating the partitions (and doing the gpart bootcode bit as above). All works. Guesses: either something is wrong with backup/restore, or having a larger = disk causes the problem. Since examining the output of "backup" doesn't indicate anything disk-size related that changes, I'm guessing that "restore" doesn'= t do quite the same thing as "create". Possibly if one did a "create" prior to the backup/restore, it might work o= ut differently. Anyway, this has been my experience, so if nothing else works and you lande= d on this page, try my "solution" and good luck to y'all. (If nothing else, it got me to create an account!) --=20 You are receiving this mail because: You are the assignee for the bug.=
