Hello,
I flashed my BIOS to F14 yesterday, but had issues getting out of S3. I'd explain the issue as Black Screen of Death on wakeup, no response, no cursor, hard power off required to solve. At first I thought it was because I had changed from Native IDE to AHCI, but after (A LOT OF!) tinkering with various drivers, I re-flashed to F13 and solved the problem!
I suppose this isn't really a question, more of a bug report/comment.
Cheers.
