I just tried the USB -> PS/2 converter and it didn’t work (might be because the port is a “mouse/keyboard combo port” according to the docs). I tried kern.cam.boot_delay=30000 and the keyboard was probed before the mountroot prompt came up so I could use it; I’ll add that tip to PR 133989.

Entering in “?” on the mountroot prompt doesn’t list any zpools (screenshot available here: https://people.freebsd.org/~ngie/bayonetta-mountroot-panic-PR-192183.jpg ). It seems like a geom or a ZFS issue.

I don’t have much to lose at this point, so I’ll try upgrading to 9-STABLE, 10-STABLE, and CURRENT to see if the issue goes away (and of course not upgrade my zpool in the process).

Thanks :)!
