Perhaps, but not limited to the 6 series boards — as I said I have the same symptoms on a Z77X-UD5H.
Well, I'll slap it in here later and try. By the way, which UEFI version are you running? Although not official, yet, F12 can be downloaded here http://forums.tweaktown.com/gigabyte/28441-gigabyte-latest-beta-bios.html
F12 doesn't appear to be a beta, as they usually have another letter after them.
That said, it also appears to be 100% stable.
Not saying it'll fix your issues though.
Coincidentally, I found that the Z68XP-D3 board I have also has issues with sleep/wake/shutdown/restart using an ASMedia ASM1042 based USB 3.0 card, so it's clearly not an issue specific to FireWire cards, but rather to some add-in PCI Express cards.
