If you have a moment to relay the bug to Gigabyte, they might take it more seriously if they get multiple reports (I've already sent them one).
I did just that today. Lets see how long it takes for them to fix it. See copy of my explanation below.
Hybrid sleep aka STR+hibernate fails to resume if the USB 3 ports are enabled in the bios but only after a power interruption while in Hybrid sleep. I've already got the latest NEC USB 3.0 driver (2.0.4.0 2010-07-22) from the Gigabyte website installed. This happens with or without any devices plugged into the USB 3 ports.
To reproduce this problem S3 and USB 3 must be enabled in the bios.
Hybrid sleep must be enabled in windows. USB 3 driver above must be installed. From within Windows 7 64 bit give windows the sleep command (in my case the sleep button on my keyboard). Once the PC is off turn the PSU switch off for 1 minute and then back on. Now attempt to resume from Hybrid sleep. All you will get is a blinking cursor. If you force a power down by holding the power switch in for four seconds then power up and jump into the bios and disable the USB 3 ports. Then save and exit, windows will resume just fine using the same saved hibernate data. I tried to duplicate this problem using regular hibernate but it does not have problems resuming after a power interruption even with the USB 3 ports enabled in the bios. I would guess this is a bios issue of possibly a USB 3 driver issue.
Note normal S3 aka STR works fine on its own (I know it can't recover from a power loss) even with USB 3 enabled in the bios.
Thanks for your time

I received a reply from Gigabyte today and they claim they can't reproduce the problem. Here is their reply.
Dear Customer
Our team had attempted to replicate your issue without any success, we tested with the below configuration:
1. Set USB 3.0 Controller as enable in BIOS and enable Hybrid sleep in Win7
2. Put the PC to sleep mode.
3. Once the pc powers down, we turn off the PSU switch
4. After few second we turn on the PSU switch and power on the system
5. The system will then show the POST screen, continue with “Resuming Windows” and successfully loads into Windows.
Please provide us with procedure to replicating your issue
Do provide your system configuration as well
Hey Gary123 did you get a reply back from Gigabyte yet?
