suspension no longer works with the latest kernel on a mac book pro retina 11,1 haswell

[Craig Magina]

Earlier in the trusty development, suspension worked fine, but after a recent update the laptop will no longer go to sleep when the lid is closed, instead the screen blanks and wifi is reset.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.14 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I found the issue was with a workaround script for network-manager. There are definitely some suspension issues with the latest kernels on this laptop however, but those have been filed as separate bugs.
