can't access PCIe card under sbc8548

hi, scott:
  Thanks for replying!

  when I use iowrite8 to write, things seem OK, the codes continue running,
  when I use ioread8 to read, the console I use freezes. The console stops
  responding.

  My PCIe card's local bus register is at BAR0+0xC7, so the driver should
access 0xfc7fc027 and the following 7 bytes. But When I access the areas:
ioread8 just freezes.
