Ok I have Ubuntu 10.04, rarely it freezes & I find no mention of it in messages (log file viewer) I see it says something about recovery in it after I reboot, but no mention on from what. This happed with my old memory, memtested & found 2 errors by test 6, this memory, no errors. I see on the Ubuntu forums some have probs. with freezing, no sources mentioned. Is there a way to get a list of hardware, from mem. it might be not exactly right. I just downloaded hwinfo, how do I open it, no shortcut was put anywhere? I have a .html file with detailed hardware info, how can I get it to anyone?? I have the hwinfo info also, but it is to long to cut & paste. I just found tis in messages from today wlan0: IPv6 duplicate address fe80::213:f7ff:fee5:83e0 detected! could that cause freezes?

What sort of hardware it is running on? I've had problems like this on my old laptop 1.5 celeron/512mb ram, it would run ubuntu 9.04 but nothing after. Either kept crashing or wouldn't load at all
 
How often does it freeze? If its frequent then just run with the wireless disabled for a bit and see if the problem goes away.

Are you overclocking? What video card are u using?

EVGA. nForce 650i ultra Intel Core 2 Duo Wolfdale E8200 2.66GHz
6MB Cache Dual Core 1333MHz 4 Gig DIMM-DRAM NVIDIA GeForce 8800 GTS with 512 DDR3 memory (PCIe 1.00 x16)

Rarely freezes.

No overclocking, I do have a Logitech Dual Action USB & USB headphones.

The memory is 2 sticks, does that matter? Some on the Ubuntu forum said test the sticks individually.

Doubt it :)
Most this really should do is kill your network connection.

Was this a clean install or an upgrade from a previous version though? I've got a 10.04 install that I upgraded from 8.04, and something really isn't right somewhere in the upgrade process. No idea where, and I haven't get round to properly troubleshooting it yet, but I've seen one complete freeze, and one instance where the xorg ate the CPU completely until I killed it via SSH.

Clean install, ya there is a post on the Ubuntu forums about 10.04 freezing, others are having prob. also. No linked cause, is there a app. to kill frozen apps. for Ubuntu like windows task manager? Sometimes when it freezes on reboot the wireless is gone & I have to unplug my dongle then plug it back in to get it back. It is a SMC EZconnect 802.11g.
 
Ah, just found the thread in question, don't normally float around on there :)
Looks to be a kernel issue from a poke through the thread; I'm currently slimming down the default config and running a custom build.

Will report back.

Nicely slimmed 2.6.35 generic kernel on there now straight from the kernel.org sources.
Will leave downloading overnight and see what happens :)

Edit:
If you're looking to kill frozen apps (As opposed to a completely dead system), then gnome-system-monitor does the same job as Windows task manager :)

Fresh kernel didn't work, but I've now turned off all the power management options, which appears to have worked. Now been up downloading for 48 hours straight :)

Will shoot whoever managed to let this into a LTS release though, seriously unimpressed :mad:

Ok, I figured something out. Just the mouse freezes, I was on Youtube, the pointer froze & the video was still playing. It Is a MS USB Intelipoint Optical, not sure exactly what type. I think it is just the normal one. What is a GUI app. for Gnome I can download to tell me hardware info??
 
Long shot, but try doing the following when the mouse freezes in the console;

sudo modprobe -r usbhid ; sudo modprobe usbhid
 
By any chance, it doesnt generally happen when you try powerdown the machine does it?

Nope, just at random points.

How do I navigate without the mouse? SuSE/OpenSuSE never had a whole system freeze with it. Oh and on boot up it took a few secs for the mouse to come on/get power to it. Where do I get a hardware info app. that will open within gnome?
 
I'd try disabling all the kernel power management features, that's definitely worked in my case :)
A freezing mouse is also one of the first symptons; If leave it, everything will gradually lockup if you're seeing the same issue.

Open up a terminal, and run this:
Code:
sudo gedit /boot/grub/menu.lst
It'll prompt you for your passsword, and the you'll then be in the grub config.
Scroll down, and find the 'Default Options' setting. Add this to the end of the last line:
Code:
noapic nolapic acpi=off
Save and close this file.
Finally, run this:
Code:
sudo update-grub

This will update grub with the new options you just set. Reboot, and they should be applied.
 
If I close firefox, I then can't open it again until I restart x. "Firefox is already running but is not responding" or something like that, but it doesn't show up under ps or top. Ubuntu is fun like that, random freezes are just part of the package.

menu.lst is blank, when I open it, plus I can't find it in the folder when I open it in Gnome.
 
Rot, you're using Grub2 then, I forgot that they only changed it for fresh installs :o
Try this instead:

Open a terminal and run this:
Code:
sudo gedit /etc/default/grub
Find the line 'GRUB_CMDLINE_LINUX_DEFAULT', and add this to the end of it (Between the " "):
Code:
noapic nolapic acpi=off
Save and close the file.
Finally, run this:
Code:
sudo update-grub
