Is there going to be a software workaround for the earlier revisions?

No, there will be a new stepping. It can't be fixed by Firmware/Software. So if you use sleepmode you need to wait a couple of months, just like the Sandy Bridge SATA Bug. Maybe some brands will allow a swap to the C2 Stepping free of charge, but this is just a minor bug unlike the SATA controller.

This wouldnt hold me back. I use S3 sleep, but dont have always on USB 3 devices for it to matter.

Does it only affect USB 3.0 devices plugged into a USB 3.0 port or will it also happen with USB 2.0 devices plugged into the USB 3.0 port? I want to buy a Haswell ultrabook when they come out and I'll be using sleep mode. I usually unplug external drives from my computers before putting a computer to sleep anyway. However, this sleep bug will cause a problem when booting from an external USB drive and the computer falls asleep. I'll just have to disable sleep if I need to boot from a USB drive.

Well, it's not important for desktops but definitely important for laptops, that's for sure. Intel hasn't really disclose the entirety of the bug publicly it seems but a lot of laptop users don't turn off their laptops when they're on the go inside a company. They need to unplug, pack, go to another room or board room and deploy. Sometimes not enough time to wait for the system to go through the boot cycle again. deltatux

This wouldnt effect me either, seeing I have never used sleep more or hibernation on any of pc ever, nor will i ever for that mater. My pc's are either On or Off. Only standby feature I use it for the monitor.

Far as i concerned it for laptops, Desktops are not ment to be lower power devices laptops are. Power saving features something desktops useless imo, Stoves,Microwaves, Washers,dryers AC, Etc and alot of othe appliances use way more power. and power a desktop draws a month is gona nothing close compared to the other stuff.

The chip is definitely broken. Unlike minor defects (which all steppings have), this one cannot be fixed. Responses like some of the above mean that Intel can get away with selling crap.

Can't be fixed? Intel will release a new stepping that will fix it. A disconnected USB device after resuming from sleep doesn't break the chip.

An SSD doesn't save me from my motherboard doing a check of every port of every controller one by one. I have about 9001 controllers on this thing. Gah, I wanted to buy a Haswell system as soon as the parts were available.

A new stepping to resolve the issue is their admission that it breaks the chip. It breaks the chip so much they have to fix it...with a new stepping. If it didn't break the chip, they would just sell the chip. Rocket science.

Huh? I did say that this is more of an issue for laptops, not desktop. What are you saying? lol deltatux

Both of my rigs my main on the Z68 and my Z77 don't take but about 10 seconds to go through its post dance the Z77 takes even less I have to start spamming delete as I'm pressing the power button to go into the BIOS. Have tried disabling everything your not using on your board?

Breaks the chip? If only you knew what other IC companies sell. It is definitely a mishap but not a deal breaker. Most of the time the decision boils down to OEM and market pressure (Time to market being a priority), it is better to have a chip with documented and avoidable problems, than to waste fab time running them under capacity. Plus consumer market standards allow chipmakers to sell chips with these problems, otherwise half the products people want would take years more to reach the market. For example like for automotive MCUs which have 5 year long product cycle (sometimes longer) with strict guidelines for mission critical applications.

Not that this particular bug would bother me personally but I find it interesting that so few people use sleep mode on their desktops. I don't turn my desktop off, ever. The power draw in sleep mode is less than my watt-meter can reliably measure and it sleeps/wakes in a few seconds rather than having to go through the whole minute-long boot process. I reboot something like once or twice a month, with the monthly Windows updates and if some other software requires it to update correctly.
