Hi,

There's currently a problem with mfi(4) on mfi_attach() calling
bio_register(). At the point on where mfi_attach() is called
the pseudo-device bio(4) hasn't been initialized so bio_register()
fails when LOCKDEBUG is used with an uninitialized lock.

I fixed another coming soon driver with the same way than the patch
I'm posting here, via a kthread that deferrs the creation of sensors
and calling bio_register() until there's thread context (and the bio(4)
pseudo-device is already initialized).

Patch attached or available at:

http://www.netbsd.org/~xtraeme/mfi_biofix.diff
