No I don't have this issue at all. Two suggestions :
- I would start by updating your BIOS to the latest version (I've seen
in your report that you are using version 1.10 that is quite old, mine
is at version 1.15).
- I this doesn't solve the issue (there's a good chance that it will),
you'll have no choice but finding the first bad kernel by using git
bisect (this means you will have to compile your own kernels -- and
manually apply the patch for the black screen issue for pre- 3.2
kernels -- this is painful but the best way to make progress in
solving your issue)

Good luck to you !
