>Description:
	The install kernels for 1.4.1 and 1.4.2_ALPHA both hang after detecting the cia device.  Further investigation has shown that they hang in cia_dma_init while setting CIA_PCI_W2BASE.  The CIA_PYXIS_BUG_BASE definition is supposed to be at 128mb, but is only defined as 128kb.  I looked through some FreeBSD sources, which do set this to (128*1024*1024).  After making this change the machine stops freezing, however, when I boot I can not access anything on my pci bus.  I can configure my onboard ethernet adapter, but I can not send any traffic over it.  This all works fine in True64/FreeBSD though.  For more information see the "More pyxis/500a info.." thread on the port-alpha mailing list.
