Hi Shannon! What is the status of the fix from Intel? I have the same problem since upgrading to 3.x series and it is VERY annoying - only way I can fix it is rebooting the kernel, so it really seems a kernel bug. Hibernating the system and doing a full power-off (unplug AC, remove battery, wait 60 seconds – this should do it) the laptop does NOT fix it, so I concur: the kernel must retain some bogus information somewhere since the hw has definitely lost its status info.
Hi Juha,Sorry, I haven't heard from him in a couple months. I think both of us are pretty backed up with other things to deal with (as an embedded systems developer, I would have just tracked it down myself if I could spare the time). One thing that seems to have made a difference for me is that I use suspend rather than hibernate these days. This seems to give me much better system stability, particularly with the iwlagn driver, though it shows a number of quirks other than this bug, at least the other ones (so far) can be cured by simply waiting and/or reloading the device driver. I'll send him a message and see what is happening.
