I don't know why the following code fails: if (pci_get_capability(sc->sc_pc, sc->sc_pcitag, PCI_CAP_PCIEXPRESS, &sc->bge_pciecap, NULL) != 0) { /* PCIe */ sc->bge_flags |= BGE_PCIE; bge_set_max_readrq(sc); }The driver iterates the while-loop in pci_get_capability() three times and returns 0 then. ChristophI'm afraid that your system has problem in the pci config registers.
In pci_get_capability() I dumped the values of PCI_CAPLIST_CAP(reg) in the while loop. The output: pci_get_capability: PCI_CAPLIST_CAP 0x1 pci_get_capability: PCI_CAPLIST_CAP 0x3 pci_get_capability: PCI_CAPLIST_CAP 0x9 pci_get_capability: PCI_CAPLIST_CAP 0x5 The first is PCI_CAP_PWRMGMT, the secons is PCI_CAP_VPD, the third is PCI_CAP_VENDSPEC and the fourth is PCI_CAP_MSI.
Could you show me the message of "pcictl pci0 dump -d 20"? It seems your are using NFS boot.
Yes.
Can you boot from a disk?
No, but sometimes it happens that the dhcp request succeeds. When that
happens the machine happens.
Here the output of
"pcictl pci0 dump -d 20 -f 6":
