  Is anybody running an Asus motherboard (specifically one with 430HX
chipset) with 512K of L2 cache?  I recently ordered 6 of these
motherboards with 256K built-in and an additional 256K on a module and
every one will crash FreeBSD 2.1.6 with the 256K module attached.  It
doesn't seem to have that problem with Windows 95 but I took the module
out anyway, just to be safe.  The following scenarios will crash it
everytime:

  512K Cache, MB set to use 512K Cache, BIOS Cache enabled
  512K Cache, MB set to use 256K Cache, BIOS Cache enabled

  If I pull out the module or disable the cache completely in the BIOS
then everything is rock solid.

  The Asus modules have the numbers CM2020R and 964109.  Any ideas?

  Thanks,

  Tim
