This does not seem to ever happen on 2.6.27-rc4. When this happens, I observe the following messages in dmesg: (AP mac masked out with XX): [16433.458084] iwl3945 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 [16433.502490] PM: Adding info for No Bus:iwl-phy4:radio [16433.502666] Registered led device: iwl-phy4:radio [16433.502764] PM: Adding info for No Bus:iwl-phy4:assoc [16433.502822] Registered led device: iwl-phy4:assoc [16433.502870] PM: Adding info for No Bus:iwl-phy4:RX [16433.503006] Registered led device: iwl-phy4:RX [16433.503055] PM: Adding info for No Bus:iwl-phy4:TX [16433.503111] Registered led device: iwl-phy4:TX [16433.505268] eth1: authenticate with AP XX:XX:XX:XX:XX:XX [16433.522344] ADDRCONF(NETDEV_UP): eth1: link is not ready [16433.704125] eth1: authenticate with AP XX:XX:XX:XX:XX:XX [16433.705986] eth1: authenticated [16433.705997] eth1: associate with AP XX:XX:XX:XX:XX:XX [16433.708406] eth1: RX AssocResp from XX:XX:XX:XX:XX:XX (capab=0x411 status=0 aid=1) [16433.708412] eth1: associated [16433.709659] ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready [16443.712280] eth1: disassociating by local choice (reason=3) [16443.712902] eth1: disassociating by local choice (reason=3) [16444.692059] eth1: no IPv6 routers present [16445.997384] eth1: authenticate with AP XX:XX:XX:XX:XX:XX [16445.999304] eth1: authenticated [16445.999312] eth1: associate with AP XX:XX:XX:XX:XX:XX [16446.001784] eth1: RX ReassocResp from XX:XX:XX:XX:XX:XX (capab=0x411 status=0 aid=1) [16446.001790] eth1: associated [16446.008222] eth1: authenticate with AP XX:XX:XX:XX:XX:XX [16446.009539] eth1: authenticate with AP XX:XX:XX:XX:XX:XX [16446.012433] eth1: authenticated [16446.012440] eth1: associate with AP XX:XX:XX:XX:XX:XX [16446.015149] eth1: RX ReassocResp from XX:XX:XX:XX:XX:XX (capab=0x411 status=0 aid=1) [16446.015155] eth1: associated [16456.017223] eth1: disassociating by local choice (reason=3) [16456.019751] eth1: disassociating by local choice (reason=3) [16458.298346] eth1: authenticate with AP XX:XX:XX:XX:XX:XX [16458.300319] eth1: authenticated [16458.300339] eth1: associate with AP XX:XX:XX:XX:XX:XX [16458.305557] eth1: authenticate with AP XX:XX:XX:XX:XX:XX [16458.314765] eth1: authenticated [16458.314781] eth1: associate with AP XX:XX:XX:XX:XX:XX [16458.318666] eth1: RX ReassocResp from XX:XX:XX:XX:XX:XX (capab=0x411 status=0 aid=1) [16458.318673] eth1: associated [16468.321210] eth1: disassociating by local choice (reason=3) [16470.604081] eth1: authenticate with AP XX:XX:XX:XX:XX:XX [16470.606122] eth1: authenticate with AP XX:XX:XX:XX:XX:XX [16470.608330] eth1: authenticate with AP XX:XX:XX:XX:XX:XX [16470.608367] eth1: authenticated [16470.608374] eth1: associate with AP XX:XX:XX:XX:XX:XX [16470.614629] eth1: RX ReassocResp from XX:XX:XX:XX:XX:XX (capab=0x411 status=0 aid=1) [16470.614648] eth1: associated [16480.617268] eth1: disassociating by local choice (reason=3) [16480.619939] eth1: disassociating by local choice (reason=3) [16482.896840] eth1: authenticate with AP XX:XX:XX:XX:XX:XX [16482.899593] eth1: authenticate with AP XX:XX:XX:XX:XX:XX [16482.899626] eth1: authenticated [16482.899633] eth1: associate with AP XX:XX:XX:XX:XX:XX [16482.906006] eth1: authenticate with AP XX:XX:XX:XX:XX:XX [16482.906048] eth1: authenticated [16482.906055] eth1: associate with AP XX:XX:XX:XX:XX:XX [16482.907625] eth1: authenticate with AP XX:XX:XX:XX:XX:XX [16482.909446] eth1: authenticated [16482.909453] eth1: associate with AP XX:XX:XX:XX:XX:XX [16482.918553] eth1: RX ReassocResp from XX:XX:XX:XX:XX:XX (capab=0x411 status=0 aid=1) [16482.918564] eth1: associated [16492.920224] eth1: disassociating by local choice (reason=3) [16492.920986] eth1: disassociating by local choice (reason=3) Reverting 8ab65b03b7893da4a49009e7e356e36e27b0c407 seems to make the card associate properly after suspend, for me. -- MST
