I'm now beginning experiencing problems as per #158468. Marking this as a duplicate. *** This bug has been marked as a duplicate of 159078 ***
======================== Hardware Affected: ======================== Some nForce4 nVidia PCI Express motherboards (Reported in this bug) Some ASUS nVidia PCI Express motherboards (Reported in other bugs) ======================== Workaround: ======================== Disable ACPI via BIOS * Hit delete when starting up * Go into advanced BIOS features * Set IO-APIC function to [disable] Diable ACPI via kernel * Press e when the grub menu appears * Use down arrow to select the line which has kernel /vmlinuz-2.6.... * Press e to edit that line * Append acpi=off to the end of the line * Press b to boot the kernel * Use root privlidges to append acpi=off in /boot/grub/grub.conf if you want to make changes permanent ======================== Reasoning: ======================== http://download.nvidia.com/XFree86/nforce/amd64/1.0-0301/KnownProblems.html Network and other devices randomly stop working when ACPI is enabled This problem may be caused by an incorrect ACPI table entry that causes the timer interrupt to be incorrectly configured. If the kernel console boot trace (viewable using dmesg) contains messages such as these: ..MP-BIOS bug: 8254 timer not connected to IOAPIC ...trying to set up timer (IRQ0) through the 8259A . failed. ...trying to set up timer as Virtual Wire IRQ... failed. ...trying to set up timer as ExtINT IRQ... works. then the incorrect ACPI table entry is present. On 2.6 kernels, this can be worked around by specifying the 'acpi_skip_timer_override' boot line option. An alternative workaround is to disable ACPI in the BIOS or by using the 'acpi=off' boot line option.
