Below I listed output > under i386 and under amd64. Perhaps you are able to get a hint? Hmm, would you be able to boot with mcfg=1 on amd64 (perhaps using nfsroot or an mfsroot) and capture this output? The mcfg thing only affects access to PCI config space (what pciconf -r is displaying). I want to be able to compare the "broken" case (amd64 mcfg=1) with a working case. > Tell me if I can help in any way. > > Thanks in advance, > Rainer Hurling > > > #pciconf -lv > atapci1@pci0:0:5:0: class=0x010185 card=0x72601462 chip=0x037f10de > rev=0xa2 hdr=0x00 > vendor = 'Nvidia Corp' > device = 'MCP55 SATA/RAID Controller (MCP55S)' > class = mass storage > subclass = ATA > atapci2@pci0:0:5:1: class=0x010185 card=0x72601462 chip=0x037f10de > rev=0xa2 hdr=0x00 > vendor = 'Nvidia Corp' > device = 'MCP55 SATA/RAID Controller (MCP55S)' > class = mass storage > subclass = ATA > > > --- i386 Config ---------------------------------------------------- > #sysctl hw.pci.mcfg > hw.pci.mcfg: 1 > > #pciconf -r pci0:0:5:0 0:0xfc > 037f10de 00b00007 010185a2 00800000 > 0000c481 0000c401 0000c081 0000c001 > 0000bc01 f9ef9000 00000000 72601462 > 00000000 00000044 00000000 01030117 > 72601462 0002b001 00000000 00000000 > 0008680f 00000000 00000000 00000000 > 00000000 00000c41 42060f00 00000000 > 40c4782c 00001001 00001001 00200020 > c0000000 0f498000 a0200000 7c750000 > a0100000 00000000 10060006 0101037f > 19000a12 00000000 00000000 02003133 > 0084cc05 00000000 00000000 00000000 > 00000000 00000000 000a000a a8020008 > 0c02000a 00000042 00000000 e7c00001 > 0c02000a 00000042 00000000 e030000f > 00000000 00000000 000c0010 00000000 > > #pciconf -r pci0:0:5:1 0:0xfc > 037f10de 00b00007 010185a2 00800000 > 0000b881 0000b801 0000b481 0000b401 > 0000b081 f9ef8000 00000000 72601462 > 00000000 00000044 00000000 01030214 > 72601462 0002b001 00000000 00000000 > 0008680f 00000000 00000000 00000000 > 00000000 00000c41 42060f00 00000000 > 40c4782c 00001001 00001001 00200020 > c0000000 ffefffff 0f1f0000 f7ff7f3b > 3fb70000 00000000 10060006 0101037f > 00000a12 00000000 00000000 02003133 > 0084cc05 00000000 00000000 00000000 > 00000000 00000000 000a000a a8020008 > 0602000a 00000042 00000000 0050000f > 0602000a 00000042 00000000 0040000f > 00000000 00000000 000c0010 00000000 > > > --- amd64 Config --------------------------------------------------- > #sysctl hw.pci.mcfg > hw.pci.mcfg: 0 > > #pciconf -r pci0:0:5:0 0:0xfc > 037f10de 00b00007 010185a2 00800000 > 0000c481 0000c401 0000c081 0000c001 > 0000bc01 f9ef9000 00000000 72601462 > 00000000 00000044 00000000 01030117 > 72601462 0002b001 00000000 00000000 > 0008680f 00000000 00000000 00000000 > 00000000 00000c41 42060f00 00000000 > 40c4782c 00001001 00001001 00200020 > c0000000 03562000 80080000 41403000 > b0080000 00000000 10060006 0101037f > 18000a12 00000000 00000000 02003133 > 0084cc05 00000000 00000000 00000000 > 00000000 00000000 000a000a a8020008 > 0c02000a 00000042 00000000 e7c00001 > 0c02000a 00000042 00000000 e030000f > 00000000 00000000 000c0010 00000000 > > #pciconf -r pci0:0:5:1 0:0xfc > 037f10de 00b00007 010185a2 00800000 > 0000b881 0000b801 0000b481 0000b401 > 0000b081 f9ef8000 00000000 72601462 > 00000000 00000044 00000000 01030214 > 72601462 0002b001 00000000 00000000 > 0008680f 00000000 00000000 00000000 > 00000000 00000c41 42060f00 00000000 > 40c4782c 00001001 00001001 00200020 > 00000000 ffefffff 0f1f0000 f7ff7f3b > 3fb70000 00000000 10060006 0101037f > 00000a12 00000000 00000000 02003133 > 0084cc05 00000000 00000000 00000000 > 00000000 00000000 000a000a a8020008 > 0602000a 00000042 00000000 0050000f > 0602000a 00000042 00000000 0040000f > 00000000 00000000 000c0010 00000000 > -- John Baldwin
