The patch you sent was not against kernel git, but I moved the debug statement from iwl-mac80211.c to iwl-agn.c (where I guess is the right place) and applied the rest of the patch. > Please also enable the MAC80211_HT_DEBUG compilation flag > I also the (HT + TXQUEUES) debug flag of the driver: modprobe iwlwifi > debug=0x84000000 Also activated. Here my very very small theory, but that is just guessing: Could it be related to the time being adjusted by ntp or something? I have the feeling it works for a bit, then hangs. In this little bit it might be that ntp updates the time of the laptop. That would explain why on a full normal reboot it most of the times work, but when the laptop sleeps for long time, or is turned of for long time, then it is getting problems. But this is surely just a stupid theory.
