Long boot delay with Intel Pro/wireless

[Mikko Ohtamaa]

Binary package hint: linux-generic

I just installed Feisty Fawn to my HP nx9420 laptop. The laptop has PRO/Wireless 3945ABG Network WLAN.

For some reason, there is very long delay (> 30s) when setting up kernel network during boot when WLAN is enabled (hardware led is lit). This happens for both during set-up and booting the real system.

Otherwise card seems to work fine. If I recall correctly, the first version of Edgy didn't boot at all when WLAN was enabled on this hardware.

Looks like Feisty kernel is 2.6.20.12.8 kernel.

You are missing a considerable amount of needed information. Please attach the output of these commands (do not paste into comment). Use the web interface:

dmesg
lspci -vv
lspci -vvn

Thanks for attentation Ben. Here is the information you wish.

The relevant part from dmesg where you see the delay:

[ 19.264000] ipw3945: Detected geography ABG (13 802.11bg channels, 23 802.11a channels)
[ 59.880000] NET: Registered protocol family 10

Also, I just confirmed that turning off WLAN kill switch will make the laptop boot faster. Just turn on WLAN when you have logged in and you save 30 second of boot time.

This looks more like a boot script issue. First, do you have linux-restricted-modules-generic installed (so that you have ipw3945d user space daemon), and also is the device configured correctly in /etc/network/interfaces?

If the latter is not true, then I suggest commenting out the entry for it in /etc/network/interfaces so that the startup scripts do not attempt to start the device (and hence, wait for it to come up, which is the cause of the delay). Then just use NetworkManager to configure the interface. Either that, or configure it correctly in /etc/network/interfaces.
