bcm4313 doesn't work/is disabled after suspend

[dr_oliver]

Hello Everyone,

I've installed Kubuntu 10.10 on a friends Lenovo B560 notebook and I ran into a Problem I can't solve by myself.

It has a Broadcom bcm4313 wifi chip and it works fine with Ndiswrapper and the restricted STA driver from Broadcom (module 'wl'). So I can connetct to my protected wireless network through NetworkManager or manually by using iwconfig and dhclient.

The Notebook has a LED that indicates if the wifi device is on or off.
Loading/unloading the module turns on/off the device and the LED.

The Problem is that the LED keeps off after resuming from suspend (to disk or ram) and the bcm4313 seems th be 'disabled'. No matter what module I'm using.
Means the interface (eth1 or wlan0 - depending on ndiswrapper or wl) exists after resuming but I can't scan or connect to any network.

I'm using the wl module right now, and this is what dmesg says about the bcm4313 after resuming from suspend to disk (which btw works fine in all other aspects)

[  268.179474] eth1: no IPv6 routers present
[  292.422057] wl 0000:04:00.0: PCI INT A disabled
[  296.270871] wl 0000:04:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
[  296.270887] wl 0000:04:00.0: setting latency timer to 64
[  296.285833] eth1: Broadcom BCM4727 802.11 Hybrid Wireless Controller 5.60.48.36

I'm not sure if it could be the PM scripts fault.
because

od@minion:~$ dmesg |grep -i 'pm: resume'

doesn't mention the wifi:

[    1.112810] PM: Resume from disk failed.

So I've treid to unload/load the module manually before/after suspend/resume but with no luck. I've got an interface, but can't use it.

The line

[  292.422057] wl 0000:04:00.0: PCI INT A disabled

EDIT: Nothing to worry about. I had the wl module unloaded before.
irritated me, and I tried

lshw -C Network

it gave me this for my wifi card:

  *-network DISABLED
       description: Wireless interface

I guess the big question is: How do I reenable the bcm4313 after suspend?

I'm using the ubuntu-kernel 2.6.35-23-generic.

Please let me know if you need to know more. I'm stuck.

Thanks and regards
