Basically, devfs as supplied in CURRENT had a 16 character limit on device names, and it didn't understand subdirectories: it treated the / as a part of the device name. Vinum device names can be much longer than 16 characters, so I changed the limit to 96 characters on my test machine, but wasn't able to get it to run reliably. I've told phk about this on IRC some months ago, but I haven't seen a commit fixing the problem. I could have missed something, of course. To help localize this problem, could you please try this same thing on a kernel without devfs? The dump you sent me did not look like a Vinum bug, as I said in my reply.
