Latest working kernel version: 2.6.25-rc4 Earliest failing kernel version: 2.6.25-rc5 Distribution: ubuntu gutsy Hardware Environment: T60p Software Environment: self-built kernel, .config attached Problem Description: Starting with 2.6.27-rc5, my T60p sometimes fails to associate with an access point after suspend to ram/resume. This does not seem to happen on 2.6.27-rc4. Steps to reproduce: suspend and resume several times. At some point the card fails to associate with the AP.

Do you use hwcrypto? Can you try the other way around?

(In reply to comment #9) > just set hwcrypto=1, right? Yes. It looks like wpa_supplicant authentication timeouts 10 seconds after association. So the STA decides to disassociate itself. I'm not 100% sure it is wpa_supplicant authentication related. Could you configure the AP to open mode (and also change your wpa_supplicant.conf setting to reflect that) and retest?
