dmesg

Looks like bug 63935 (that about Macs booting in EFI mode) but this one about
non-EFI laptop (Acer Aspire 7560G with BIOS v2.04). Ubuntu 13.04 x86_64, Linux
3.10.rc4. SUMO2 UVD firmware updated from April 2 (I can't find TURKS UVD
firmware - it's use same firmware as SUMO2?)

$ lspci -nn | grep VGA

Whistler [Radeon HD 6600M/6700M/7600M Series] [1002:6741]

As I undersand UVD initialized successfully on first GPU (look into attached
dmesg) but can't initialize on second - boot stuck for ten seconds.
