F13: No wireless after suspend using iwl3945

Hi,

My Vaio suspends just fine and wakes up everything except my wireless card. It seems it is completely dead - not just unable to scan for networks.

This is what I see after resume:

iwl3945 0000:06:00.0: Refused to change power state, currently in D3
Jun 14 21:49:59 dillinga NetworkManager[1289]: <info> waking up...
Jun 14 21:49:59 dillinga NetworkManager[1289]: <info> (wlan0): now managed
Jun 14 21:49:59 dillinga NetworkManager[1289]: <info> (wlan0): device state change: 1 -> 2 (reason 2)
Jun 14 21:49:59 dillinga NetworkManager[1289]: <info> (wlan0): bringing up device.
Jun 14 21:49:59 dillinga kernel: iwl3945 0000:06:00.0: MAC is in deep sleep!. CSR_GP_CNTRL = 0xFFFFFFFF

<repeated multiple times>

Jun 14 21:50:00 dillinga kernel: iwl3945 0000:06:00.0: BSM uCode verification failed at addr 0x00003800+0 (of 900), is 0xffffffff, s/b 0xf802020
Jun 14 21:50:02 dillinga kernel: iwl3945 0000:06:00.0: Wait for START_ALIVE timeout after 2000ms.
Jun 14 21:50:02 dillinga NetworkManager[1289]: <info> (wlan0): deactivating device (reason: 2).

I'm currently running on 2.6.33.5-124.fc13.i686 with iwl version:

filename: /lib/modules/2.6.33.5-124.fc13.i686/kernel/drivers/net/wireless/iwlwifi/iwl3945.ko

Anyone else found this?

Thanks,

Maybe. Try manually removing the wireless module with modprobe, and then immediately reloading it with modprobe. Give NetworkManager a several seconds to go back to work, and then check for reconnection or for available networks. If that works, you can create a script in /etc/pm/sleep.d to automate the process. See how neeravbm did it with the b43 module here...

Thanks Stoat. I have actually experimented with rmmoding iwl3945 prior to suspend and probing it straight after but I still get the same message repeated.

Going to try rmmod and then turning the wireless off with the switch first..
