Toshiba Laptop Page Fault in pccard_scan_cis

	I have an old Toshiba laptop (225 CDS) that's been working fine with 
PCMCIA cards until I upgraded to -CURRENT. In 4.8-RELEASE, FreeBSD 
recognized the slots fine, and detected the cards as well. However, in 
-CURRENT, it doesn't detect the cards or the slots. In 4.8, the cards 
were in the mode "PCIC-Compatible" in the BIOS. This mode didn't work 
with -CURRENT, and so I turned it to "CardBus/16-Bit". -CURRENT 
recognizes the slots, but whenever a card is present on bootup or when 
one is inserted (after loading the modules) I get the following page fault:

I've looked on Google and found a few threads detailing this discussion, 
but the thread ended with "Oh, with some card/bridge combinations, we 
don't map the CIS address space correctly." The man pages don't say 
anything about this.

Any help would be greatly appreciated.
