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 00:01.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI BeaverCreek [Radeon HD 6620G] [1002:9641] 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI 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.
