I actually ran into this problem on some diskless booting boxes, but it went away so I assumed it was a local nit since I was messing with VFS substantially on the boxes in question. Apparently not. (This was a month or two ago, and quite pre-GEOM as default). Here's my first suggestion: the root file system is mounted by the init process--your trace shows the stack of the current interrupt thread for keyboard I/O, since that's the foreground thread when you break to the debugger. Try using 'trace 1' to trace init instead; also, if you could provide the output from the ddb ps command, that would be very useful. BTW, you really want to be using a serial console for this sort of thing -- copying stuff out by hand is (a) a pain, and (b) very error prone :-).
