I have tried in the grub.conf file noapic and apic=off I am still getting the same error message about ACPI in the dmesg output. example: ACPI: PCI interupt .... IRQ 16 eth0: RealTek RTL8139 ... IRQ16 eth0: identified 8139 chip type so ACPI is grabbing IRQ 16 and not letting eth0 have it. (I Think). How do I correctly disable it on my compaq v2000 laptop. I think it is not allowing my usb and realtek network to function. Jerry -------------- next part -------------- An HTML attachment was scrubbed...
