As said previously, this seems to be exactly upstream kernel bug http://bugzilla.kernel.org/show_bug.cgi?id=9147
I have worked around the problem by unloading modules 'ac', 'battery' and 'thermal'.
Also, problem appears when there is intensive use of ACPI events (e.g. when on battery) and/or when using the wireless adapter.
I agree with Sardar that IT IS VERY WEIRD that problems does not arise in Windows but only in Linux.
On the kernel bugzilla I have suggested, upon G. Schmitt's hint, to use an approach similar to that in kernel bug http://bugzilla.kernel.org/show_bug.cgi?id=12021 with a modified version of this patch http://bugzilla.kernel.org/attachment.cgi?id=19301&action=view
Perhaps Windows already fixes the key-up event for this hardware? Or the problem relies in the EC tables? Who knows...
