Hello. I'm sitting at home because I'm on call tonight. So I did some more work on the reboot and shutdown problem I'm having with my R100 laptop under Ubuntu 8.10.
Here is what I've found. The problem appears to be related to the WIFI adapter in the machine. There is a switch on the side of the laptop which allows you to enable and disable the WIFI adapter in the laptop. If the adapter is off then reboot and shutdown work fine, if it is on then reboot and shutdown result in the blank screen I described in my initial note. The laptop uses an Intel Pro/Wireless 2100b. The kernel module is ipw2100. I noticed whether the switch is on or off the kernel module remains loaded. I also did some experiments with ifconfig. I left the switch on and manually downed the wireless interface, which is eth1, using "ifconfig eth1 down". I then attempted to reboot the laptop and had the same result, blank screen no reboot. The only thing which seems to solve the issue is flipping the switch off before rebooting or shutting down. Armed with this new information I did some more forum searches and found some hints that it could be related to the ALSA sound subsystem. They suggested putting explicit "ifconfig eth0 down" and "ifconfig eth1 down" lines into the stop section of the ALSA-UTILS init script. That didn't fix the issue. I didn't expect it would either since my system does successfully halt. Based on this information does anybody else have any ideas on what might be going on here? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Greg King Sent: January 17, 2009 1:35 PM To: [email protected] Subject: Re: [clug-talk] Ubuntu Reboot Difficulties > Date: Sat, 17 Jan 2009 00:31:21 -0700 > From: "Craig McLean" <[email protected]> > Subject: [clug-talk] Ubuntu Reboot Difficulties > To: "'CLUG General'" <[email protected]> > Message-ID: <90b9226ab74045bfa59428aa626bf...@wiseone> > Content-Type: text/plain; charset="us-ascii" > > Hello. > > I just upgraded one of my laptops to Ubuntu 8.10.

I googled around and found a couple of potential fixes, one being a patch that was already on, and the other an X system setting to restart X on logout which seemed to work. I'm a little hazy on the detail now, but if you google "ubuntu shutdown hang" I think you'll find quite a few folks have experienced it. _______________________________________________ clug-talk mailing list [email protected] http://clug.ca/mailman/listinfo/clug-talk_clug.ca Mailing List Guidelines (http://clug.ca/ml_guidelines.php) **Please remove these lines when replying _______________________________________________ clug-talk mailing list [email protected] http://clug.ca/mailman/listinfo/clug-talk_clug.ca Mailing List Guidelines (http://clug.ca/ml_guidelines.php) **Please remove these lines when replying
