The Ethernet USB adapater which comes with the ASUS UX31 and UX21 models is the Asix "USB to Fast Ethernet" adapter, model AX88772B. At the present, the device is not recognized by the currently available kernels.

• http://www.asix.com.tw/FrootAttach/driver/AX88772B_772A_760_772_178_LINUX_Driver_v4.2.0_Source.zip

Once downloaded, the source needs to be compiled. First unzip the file.

Download essentials

apt-get install build-essential linux-headers-`uname -r`

Next, go into the unzipped directory and compile the source as follows:

cd AX88772B_772A_760_772_178_LINUX_Driver_v4.2.0_Source

make

Install the just compiled module:

sudo make install

Finally load the module:

sudo modprobe asix

That's it. You should be able to connect using a wired connection now.

Replace asix.c with the following file:

According to the intel-gfx list, the problem with rc6 seems to be related to VTd support, aka. virtualization. Adding "intel_iommu=off" to kernel boot line disables VTd, and should make rc6 stable, according to the reports

And got the screen working on 3.2-rc3 with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.modeset=1 i915.i915_enable_rc6=1 pcie_aspm=force"
