from a month ago:

john polstra, hero of the revolution, figured it out for me as follows:

jp> I think the problem may have been caused by the removal of
jp> compatibility with the old "wd" device in this commit:

jp>       
jp>       Enable WC as default again, having it off hurts too much.

jp> You might be able to work around it without backing out this change.
jp> Try this:
jp> 
jp>     cd /usr/compat/linux/dev
jp>     mv hda hda.old
jp>     mknod hda b 30 0x00010002
jp>     chown randy:wheel hda
jp>     chmod 644 hda
jp> 
jp> The 30 is the block major number for the "ad" device.  Block device
jp> support was removed from -current, but it is still present in -stable.

this fixed it.  but what the heck are we gonna do when we go to 5.0?
