New Revision: 190590
URL: http://svn.freebsd.org/changeset/base/190590
Log:
fix a bug that it passed a incorrect flag BUS_DMA_ALLOCNOW to create
a device specific DMA tag. On amd64 it could exhaust all of bounce
pages when bus_dma_tag_create(9) is called at malo_pci_attach() then as
result in next turn it returns ENOMEM. This fix a attach fail on amd64.
