In my bios I have PnPOS=NO, USB-IRQ=Disabled. The commit below results in a PCI interrupt storm and a terminally wedged system right after interrupts are enabled. Poul-Henning | nsayer 2000/12/03 09:07:24 PST | | Modified files: | sys/pci ohci_pci.c uhci_pci.c | Log: | We now have the ability to assign the correct IRQ when PNP-OS is turned | on. So stop failing the attach if the IRQ is unassigned. With this | patch, I can now boot with PNP-OS YES in my BIOS no differently than | PNP-OS NO (which is a good thing since Windows hangs with PNP-OS NO). | | Obtained from: msmith | | Revision Changes Path | 1.21 +1 -11 src/sys/pci/ohci_pci.c | 1.32 +1 -11 src/sys/pci/uhci_pci.c -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
