Bug#636355: iwl4965: "MAC is in deep sleep!" freezes
Package: linux-source-3.0.0
Version: 3.0.0-1
Severity: important
Hi.
Since some time now I get have the following problem:
When I bring the WLAN interface up, after some time (usually just minutes)
I get the following error (during which the system completely freezes for some 10-20s)

And so on...
Eventually it comes back,... but only for some time until the same happens again.
Bringing the interface down, everything's ok again.
There was no particular change, neither in kernel version, nor firmware, nor my custom kernel config.
The only change was that a damaged mainboard of the notebook was replaced by a new one (of the same
type, I guess).
It's a Fujitsu Lifebook E 8410.
Any ideas?
Thanks,
Chris.
