Major problems on Dell Latitude D600 laptop

Bug #50683 reported by FuturePast on 2006-06-22
Affects Status Importance Assigned to Milestone
xorg (Ubuntu)

Bug Description

At some point before the final Dapper release my setup broke.

Symptoms were:
CPU soft lockups (sometimes mentioned tg3, so I disabled my NIC in BIOS)
Random freezes in X (mostly within 10 mins of normal use)
Continually jerky mouse movement
CPU scaling constantly on full
Laptop overheating
Broken suspend

I stuck it out hoping for a fix, but nothing changed.
In desperation I got out an old CD of Dapper LiveCD Beta 2 and booted from it and lo and behold a rock-solid, stable system.
I re-installed from the Live CD; again a stable system.
I re-enabled the NIC in BIOS; no problem.

Next step:
Upgraded to latest kernel 2.6.15-25-686; no problem.
Upgraded rest of distro except for the packages listed below; rock-solid.
Locked versions:
xserver-xorg (7.0.0-0ubuntu32)
xserver-xorg-core (1:1.0.2-0ubuntu6)
xserver-xorg-driver-all (7.0.0-0ubuntu32)
xserver-xorg-driver-ati (1:
xserver-xorg-driver-i810 (1:

So, by elimination, the problem must be something to do with changes made in X since the versions specified above.

Any ideas or steps to take to resolve this?

I also have the same problem. It is mentionned in the following forum thread:

As said, it occurs mainly at my parent place where I do use Wi-Fi and mainly this is happening when I am on battery.
My system information is described in much detailed in both thread (my user name is the same on the forums and on launchpad.)

As the person mentionned it above, the CPU soft-lock-up is displayed in the log often around tg3 entries.

Yup, I've got the same problems with an almost identical computer. Only difference is I have 512 MB of RAM and a 30 GB hard drive. I mostly get soft lock-ups, random freezes, and broken suspend.

One more addition: I thought during the Dapper testing that this problem was related to my WiFi card, so I was following closely this bug report which was looking similar:

maybe this could be a hint...

Well, guys, I don't know what to say.
I now have a fully working, up-to-date system.

I took the following steps (as well as the ones mentioned above):
Removed xserver-xorg-driver-all and xserver-xorg-driver-i810 (and a lot of other drivers).
Upgraded xserver-xorg-core to latest.
Upgraded xserver-xorg-driver-ati to latest.
Upgraded xserver-xorg to latest.

The only other thing I did was remove and replace the memory and wifi card and completely removed the conexant modem.

This doesn't really resolve the cause of all the problems, but I no longer seem to be affected.

FuturePast, can this bug be closed?

From my side, I had my motherboard changed and Ubuntu re-install from scratch. And it rocks. No more problems neither.

Yes. I also believe this is a hardware problem.

Marked as rejected owing to comments re this being a hardware problem.

Thought about "fix released", since original report seemed to imply a pre-release version of Dapper.

Changed in xorg:
status: Unconfirmed → Rejected
