The BUG() is popping in include/asm/pci.h:pci_map_sg(). If either sg_list.address
or sg_list.page is not NULL, or both are NULL the BUG() is called. The reason
for this is around 2.4.13-pre2 bounce buffers along with a nasty memcpy where added
in linux/drivers/scsi/scsi_lib.c:scsi_io_completion() to scatterlists for HighMemIO
support, along with two extra members (page & offset) to struct scatterlist in
include/linux/scatterlist.h.
