Comment (by alexander.wetzel@…):

 First, setting nohwcrypt=1 has shown to be ineffective after all.
 I kept the rekey timeout at 5min and had the same problem as without the
 kernel parameter during normal operation.

 It looks like the "workaround" is at best reducing the chance to be hit by
 the problem and at worst is caused by some testing issue.

 I've now updated to trunk (r44510), compiled from sources to an custom
 image and gave it a quick test today. Unfortunately this version shows the
 same problem as the stable version. Setting nohwcrypt=1 is also not
 helping.

 I really would appreciate some pointers how to debug that further. Is
 there maybe a way I can dump the encryption keys on openwrt from wpad?
 It looks like the wpa_supplicant on the client is able to output keys, so
 we could compare if they agree and this is really an issue of the wifi
 card or this is a wrong assumption...
