NetworkManger freezes the pc at session stratup

[Zenigata]

Binary package hint: network-manager-gnome

Since today (06/29/07) update of network-manager-gnome, My laptop freezes badly (even the alt+impr+E/S/B keys do not work) when NW tries to get an ip adress (I think)

I can work around the problem by killing NW before login in to my gnome session, then I am able to start the wifi connection via console without any problem.

When the pc freezes, the capslock LED blinks. I had similar problem when my upgrade to gutsy was not complete and this was due to not up to date network-tools package.

The freeze seems to happen just when NW is getting the ip (first guess, need to check it) because the first green light is lit sonce quite a while (means association to wifi access point I think) then it freezes.

It is maybe linked the my wifi card (an Aheros card), but I don't know, I give the lspci and lsmod result ;

Oh, it also seems to happen mainly at startup (I have been able to launch NW after start of session and manual copnnexion and to use it to reconnect) but not only, since my PC froze during the night.

It is maybe linked to connection to a protected network (WEP tested for now), but I cannot ensure this.

It seems that this bug is somehow correlated with NWM difficulties to associates with the AP. bug https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/122761

but should not be the same thought.

Well I have not been confronted to that problem since two days, so it is maybe fixed.

(I do not have access anymore to the network where it occured thought)

Hi there
