Hi!

In -next... after few days of usage with suspend and resume cycles,
wifi failed on thinkpad x60. I have not seen this in years...

(Yes, my AP has funny hw address; but its other hw address fails, too).

Any ideas?

Suspend+resume fixed the problem.

Hi

Site note: Intel folks do not support iwlegacy, I removed them from CC.

We do not have any recent iwlegacy changes except cosmetic
ones, so this problem most likely is mac80211, pci or other
subsystem issue

It is not reproducible? If so, I think it will not be 
easy to identify the issue.

Thanks

So far it happened once... so I don't know about reproducibility. And
I'm not even sure if I'm using iwlegacy driver. Am I?

iwl3945 (and iwl4965) are iwlegacy drivers.
