Any updates on Intel 6 series + S3 bug?

[ntydon]

I assume most people are familiar with this one, but perhaps I am mistaken in how widespread this is/was.

Essentially, there is a bug with sleep/standby mode on P67/Z68 motherboards when PLL overvoltage is enabled. The system will occasionally (I estimate it's a 20-25% chance) crash on wakeup.

Many motherboards have BIOS updates supposedly addressing the issue. e.g., from ASUS P8Z68-V Pro:

P8Z68-V PRO 0706 BIOS
1. Fix FW54P PCI card compatibility issue
2. Fix the bug that the OEM activation version OS of window7 will hang at the "blue screen" if some graphics cards be installed in system.
3. Fix USB Keyboard 3R-FKB3010UBK can't work issue
4. Fix Microsoft V1 receiver can't work issue
5. Fix S3 can't resume if CPU PLL over voltage is enabled.
6. Fix the CPU and Chassis Fan speed will over the duty cycle setting range.
7. Fix CPU ratio always keep at lowest after S4 resume and AC power lost.
8. Improve DRAM compatibility.
9. Support new CPUs. Please refer to our website at: http://support.asus.com/cpusupport/cpusupport.aspx?SLanguage=en-us

Back in Sept 2011.

Except the fix doesn't work, at least not completely.

I'm just wondering if there has been any further news/progress on this bug? Obviously one solution is to disable PLL overvolt, but some CPUs only achieve stability once it's enabled. Another solution is to move to Haswell, but at this point it's probably better to wait for Broadwell in late 2014 if 5-10% IPC gains are all that can be expected.
