[Bug 946311]

[Daniel Wagner]

I have a new Macbook Air 2012 Model and it seems that I have the same
problem as reported here.

An older kernel version 3.3 works fine, where as newer ones give me a
black screen.

Daniel asked me to test the latest patch from here. I applied Check
combined VBT/register delay on top of todays drm-intel-next (20d5a540
drm/i915: don't grab dev-struct_mutex for userspace forcewak).

Eventually the screen is black again. But there is a small difference:
before it turns black I see kernel boot message (booted without the
'quiet' argument).

[Bug 839157] Re: Bluetooth applet (OBEX send/browse) does not work since Natty (after bluetoothd 4.84 exactly)

[Daniel Wagner]

This should now be fixed with a kernel patch. The 3.3 and newer contains the 
fix and for the stable
branches wait for those two commits to appear in the next release.


3.2-stable review patch.  If anyone has any objections, please let me know.

commit 18daf1644e634bae951a6e3d4d19d89170209762 upstream

Commit 330605423c fixed l2cap conn establishment for non-ssp remote
devices by not setting HCI_CONN_ENCRYPT_PEND every time conn security
is tested (which was always returning failure on any subsequent
security checks).

However, this broke l2cap conn establishment for ssp remote devices
when an ACL link was already established at SDP-level security. This
fix ensures that encryption must be pending whenever authentication
is also pending.
