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.

Any ideas?

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.

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?
