System freezes : Ubuntu Hardy Heron beta

[Raghvendra Sharma]

Hi,

Its been three days since I got this beta up and running on my Core 2 Duo T7300 system (I chose 64bit editiion), and didnt had any problems at all.

Today, while I was midway extracting a relatively large archive file (about 150+ Meg Eclipse tar), the system just froze.

I could move my mouse and keyboard lights still responded, but there was no response from system of either keyboard or mouse events.

I simply had to cold boot the system.

Now after reboot, it looks ok again (sending this report from the same system)...
Is there a way to collect info on the last freeze ? Some kind of info collection for bug filing ??

could be one off thing, or could be something else...

Exactly the same thing happened to me twice now. it works fine 99% of the time but sometimes will just freeze. Never happened on Gutsy and never happens on WinXP either.

I thought it might be SATA-related since the hard drive light flashes once every couple of seconds while it is frozen. I can move the mouse pointer around the screen but I cannot do anything else. I tried Ctrl-Alt-F1 to drop to console, Ctrl-Alt-Backspace to reset Xorg, even Ctrl-Alt-Del didn't work!

After a cold boot (hard power down) it all works fine.

I am running an Athlon XP 2800+ on a Gigabyte board with 1.5GB RAM, a Seagate SATA drive. Graphics is an ATI Radeon 9200.

It is not a fresh install, I upgraded to Hardy from Gutsy 7.10.

Applications I had open at the time (both times) were Gnome-terminal, Nautilus, Gedit, Evolution, Firefox and OpenOffice Writer.

I'm having the same problem on my HP xw4400 Workstation ... Freezing of my Hardy Heron. Only the mouse is moving but that's it.
It's already the fifth time I have to hard reboot in three days ...

Any progress on this item?

I'm looking at this now ... probably is the reason ... https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/176589

can you confirm it is a duplicate? is it still bothering you?

[Bill Michaelson (t-launchpad-bill-from-net)]

I have the same issue with 8.04, but I'm running XEN, if it matters...

root@flipper:~# uname -a
Linux flipper 2.6.24-19-xen #1 SMP Sat Jul 12 00:15:59 UTC 2008 x86_64 GNU/Linux

In my case, I have worked with various combinations of PS/2 and USB mice/keyboards. I usually work with a USB keyboard and mouse and a PS/2 port-attached mousepad. When the freezes occurred initially, it would behave similarly to what is described above, with the system continuing to run, but unresponsive to keyboard (USB) events and mouse (USB) clicks, although usually the mouse movement was still detected and the cursor moved about. Interestingly, the mousepad on the PS/2 port continued to function, and if I plugged a PS/2 type keyboard into the machine, it would work too, enabling me to regain control of the crippled machine. During these freezes, I am also able to ssh into the box and recover via reboot too.

Then I tried using only the PS/2 input devices, but the freeze occurred only a few minutes after starting. In this case, I was able to plug the USB keyboard and mouse in and continue operating that way!

So far, that's all I know. I guess this casts suspicion on a particular layer of mouse/keyboard logic. I hope this gives helpful clues to whomever might be able to fix this problem.

Further to the above, see attached lshw output. Anybody wants more info, I am at your service.

[Michael Nagel (nailor)]

you should file this against the kernel and/or xorg packages (whatever you think is responsible) to get some attention by the developers/maintainers because the are probably only tracking their packages.

[Michael Nagel (nailor)]

is this still an issue? did you decide a relevant package?

It hasn't happened for a long time. Unfortunately since the problem was
so random and I have been applying the usual Ubuntu updates as well as
having upgraded my motherboard in my PC, I can't really tell for sure at
what point the problem went away.

closing, no debugging will take place here....

[Bill Michaelson (t-launchpad-bill-from-net)]

This freeze still occurs on my system which is running Heron/Xen and current patches.

I seem to have averted it by assigning a single CPU to each VCPU and pinning them. But Friday I ran for the first time in several months without that particular CPU restriction in effect, and the keyboard and mouse froze within hours, requiring reboot to recover.

Maybe there is a clue here.

[Michael Nagel (nailor)]

forwarding to xen, looking if they have an idea...

[Bill Michaelson (t-launchpad-bill-from-net)]

Perhaps. My speculation is that Xen provides a work-around by enabling one to pin the CPUs. But maybe the problem is related to multiprocessing vis-a-vis X11.

One question to ask is whether this occurs on any single-processor systems.

Anybody?
