Err, amd64 and PAE are the same problem for drivers (dealing with 64-bit physical addresses for DMA which can require bounce buffering if your hardware only supports 32-bit physical addresses). The fix is to use the bus_dma abstraction in the driver instead of directly using vtophys() and a driver needs that fix for both PAE and amd64. amr(4) should work fine with both PAE and amd64 with > 4GB of RAM. -- John Baldwin _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
