Hi,
Here's an interesting issue, apparently Core i5 and i7 have problems after resume from suspend/standby.
I wonder whom at Intel I should let know about that.

--- Comment #3 from Thomas Bächler <[email protected]> 2010-03-18 18:42:26 --- I have only tested 2.6.33 and 2.6.33.1, as this machine is quite new. Besides other unrelated suspend problems, I can always reproduce this one on a Core i5-520M, the symptoms are exactly the ones that Florian describes.
The diversity of hardware and different kernels here suggests that this is a general problem with the i5 and i7 CPUs on Linux. Also interesting is that Florian is using an i7 of the 2009 generation, while I use the 2010 i5 CPU and the bug is the same on both.
On the same kernel(s), my old Core 2 Duo CPU has no trouble after resume, all cores are still being used as usual.
If you need any more info, I think we will be able to provide anything you need. Maybe it might also be useful to bring someone from Intel in on this.
