Do you have a prefmem resource whose limit is below 4G? A few small glitches don't surprise me as the 64bit support in the resources is new, and I am still refining it. And it should be suboptimal for multiple HT chains. (Because I am artificially limiting them in the PCI_DOMAIN). However. I don't know of a case that would assign prefmem and mem the same base address. In src/northbridge/amd/amdk8/northbridge.c:pci_domain_read_resources You might try setting the limit to 4G - 1 == 0xffffffff An lspci -vvv of the failing system would be interesting if you have BIOS under which it boots. > PCI_DOMAIN: 0000 00 <- [0x0000001000 - 0x0000005fff] io > PCI_DOMAIN: 0000 01 <- [0x00f8000000 - 0x01007fffff] prefmem > PCI_DOMAIN: 0000 02 <- [0x00f8000000 - 0x00fe6fffff] mem > PCI: 00:18.0 1c0 <- [0x0000001000 - 0x0000003fff] io <node 0 link 0> > PCI: 00:18.0 1b8 <- [0x0000000000 - 0x000fffffff] prefmem <node 0 link 0> > PCI: 00:18.0 1b0 <- [0x00fc000000 - 0x00fe1fffff] mem <node 0 link 0> > PCI: 00:18.0 1da <- [0x0000004000 - 0x0000004fff] io <node 0 link 2> > PCI: 00:18.0 1aa <- [0x0100800000 - 0x01007fffff] prefmem <node 0 link 2> > PCI: 00:18.0 1a2 <- [0x00fe200000 - 0x00fe4fffff] mem <node 0 link 2> > > PCI: 00:18.3 94 <- [0x00f8000000 - 0x00fbffffff] mem <gart> > PCI: 00:19.3 94 <- [0x00f8000000 - 0x00fbffffff] mem <gart> > PCI: 00:19.0 1c8 <- [0x0000005000 - 0x0000005fff] io <node 1 link 0> > PCI: 00:19.0 198 <- [0x00f8000000 - 0x01007fffff] prefmem <node 1 link 0> > PCI: 00:19.0 190 <- [0x00fe500000 - 0x00fe6fffff] mem <node 1 link 0> For reference on my HDAMA with a mellanox HCA plugged in I am getting: PCI_DOMAIN: 0000 00 <- [0x0000001000 - 0x0000002fff] io PCI_DOMAIN: 0000 01 <- [0xfcf0000000 - 0xfcf87fffff] prefmem PCI_DOMAIN: 0000 02 <- [0x00f8000000 - 0x00fd3fffff] mem PCI: 00:18.0 1b8 <- [0xfcf0000000 - 0xfcf87fffff] prefmem <node 0 link 0> PCI: 00:18.0 1c0 <- [0x0000001000 - 0x0000002fff] io <node 0 link 0> PCI: 00:18.0 1b0 <- [0x00fc000000 - 0x00fd3fffff] mem <node 0 link 0> Eric _______________________________________________ Linuxbios mailing list [EMAIL PROTECTED] http://www.clustermatic.org/mailman/listinfo/linuxbios
