FreeBSD 8.0 not detecting hot swap drive insertion

It should be noted that my raid controller driver (htprr) is exhibiting
the same issue. Before 8.0, both the ata and htprr drivers would
recognize a HD insertion and the disks information would be scanned and
device nodes created. On 8.0, the best I can see is that the drive
insertion is detected (the htprr driver prints a message about drive
insertion/removal), but the disks are never scanned for drive
information nor device nodes created.

P.S. My apologies if I posted this twice. I didn't see it get to the list.
