Hi all, I have an Acer Aspire 1802WSMI, 2Go RAM, ATI X600 Mobility, Wifi (NDISWrapper), Pentium 4 HT 3.0GHz, Ubuntu Feisty.
I had the same problem; Although freezed (as described in previous posts) sometimes the computer was still remotely (ssh...) accessible sometimes not. Though it did not entirely solved the issue, this helped: 1/ add kernel directive "noapic" in the kernel's startup options (/boot/grub/menu.lst). 2/ stop using Beryl... Since I did 1/; the problem never occurred when not running Beryl!!! When using Beryl, it still occurs, but far less frequently. SIDE EFFECT: sometimes, the synaptic hardware (touchpad & laptop's keyboard) do not initialise properly at boot time! As a result, I end up in front the GDM screen without being able to log in or do anything whatsoever (no keyboard). Luckily, as I'm using an external usb mouse, I still have some control and I'm able to reboot. Note that sometimes I need to do it several times before it succeeds to initialise the synaptic hardware... This problem occurs almost systematically when I have my external usb HDD connected to the laptop. Unplugging the HDD helps reducing the frequency of this nasty side effect. For now I live with this problem because I prefer it to random freezes... Hope this will help. Cheers, Manu -- Uhhuh.
