Yeah I've discussed this earlier on this topic. Quick solution so far is to use Legacy mode, and/or plug/unplug in sleep.

The better solution is to hard reset EC, wipe bios and reset factory settings.

We still dont know what causes this though, and why it manifests only on specific devices.
 
This is very interesting, but now we have to understand if it's an incompletely patched DSDT and why only on a few computers. Mine, for example, never did it.

Compare battery data in ioreg?

Ok, further testing showed that it had nothing to do with the menubar icon after all.
The fix should be repeatable this way now:
1. Boot into OSX (doesn't matter if plugged or unplugged)
2. Apple -> Sleep, and wait until the power LED goes off
3. Invert the power state (Plug in the AC if you hadn't, and vice versa)
4. Turn machine back on
And now you should be able to hotplug the power on-the-go!

Makes it sound like a problem in ACPI...
 
I wish this were the case; if so it would mean that its not (necessarily) a hardware issue.

I've attached my ioreg. What I can say is that even after I've successfully removed the freezing problem by resetting EC, and wiping BIOS, it eventually creeps back.

Here are my ioreg files as well. I saved a copy just before applying the "fix" and another just after it. I couldn't notice any significant difference but maybe it is also useful.
