Insprion 14z - UEFI boot hangs at purple screen if NIC activated
Here's my weird problem, with a UEFI Ubuntu 12.10 64 bits installation on an Inspiron 14z ultrabook with an integrated Atheros AR8162 ethernet card (NIC).
If the AR8162 card is enabled in BIOS, Ubuntu won't load, as it will hang in a blank purple screen or, in recovery mode, at "loading initial ramdisk". If the AR8162 card is disabled, it will boot just fine. The problem is that I need an ethernet connection...
What is strange is that I'm able to boot Ubuntu in legacy mode with the AR8162 enabled in BIOS and this card is working just fine with the alx module available in compat-wireless package (see: http://askubuntu.com/questions/15722.../231715#231715). The only thing is that I want to keep dual booting with Win8, so UEFI Grub installation is mandatory.
Any idea someone on how to boot Ubuntu 12.10 in UEFI mode, with a working AR8162 card?
