After my build died due to filesystem corruption I have spent countless hours trying to reinstall Lion. I've narrowed it down to a faulty nic (onboard nic). Every time I try to rebuild iAtkos L2 with the drive for this nic the machine fails to boot into the desktop. Even if I install Lion without this kext at first and install later the machine just freezes. So I got around that by using a USB wireless NIC (RealTek RTL8192SU which I obtained the drives from http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=48&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true#2317
Now my machine can not sleep (Screen goes black and drives appear to shutdown but fans still continue to run). I do not have any USB3 drivers installed and for Audio I'm using patched ALC8xx and Rollback kexts (From Multibeast) with proper DSDT coding.
My guess is it may be the wireless drivers that could be causing this but I'm not certain as I did obtain them directly from RealTek.
Attached are a kextstat dump and my dsdt.
Edit: I fixed this issue, forgot what I did but its no longer an issue.
