I have been using this method with my Averatec model 3250HX-01 without incident for the last week. However, you need to follow these steps first: 1) edit /boot/grub/menu.lst as root ( sudo nano /boot/grub/menu.lst ) 2) Look for the first section similar to: title Ubuntu, kernel 2.6.xxxxxxx-k7 root (hd0,2) kernel /boot/vmlinuz-2.6.xxxxxxxxx-k7 root=/dev/hda3 ro quiet splash initrd /boot/initrd.img-2.6.xxxxxxxx-k7 savedefault boot 3) At the end of the "kernel" line, add "acpi=noirq" so it looks like this: kernel /boot/vmlinuz-2.6.xxxxxxxxx-k7 root=/dev/hda3 ro quiet splash acpi=noirq 4) Save the file, reboot the machine Once you have rebooted, you will have network capabilities. Perform a full system update / upgrade, including kernel. The menu.lst file should update itself accordingly and the new kernel versions from now on will include the equivalente acpi=noirq option. -- IRQ 11 disabled, no network, desktop / kernel freeze (Averatec laptop) - regression from Breezy https://launchpad.net/bugs/34958 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
