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.
