LG Laptop hangs HARD [gutsy+feisty]

[peruron]

My machine often hangs completely - screen stays on, but machine becomes completely unresponsive - Ctrl+Alt+Del, Alt+SysRQ+B... nothing makes it budge but a 5-second press on the power button (hard poweroff). Tried reinstalling, and it even crashed once within the installer (before partitioning, thankfully). The crashes seem to be random, and /var/log/messages reports nothing but "---mark---" before the crash time. Please help :(

LG F1 Pro Express Dual (Core 2 Duo)

Does the system seem to continue working in the background, or are you able to SSH into the system while it is locked up?

There are some reported issues with Xorg hanging and blocking all input while the kernel continues to run in the background.

No SSHing into it when hangs, just checked today (that's not to say it didn't hang from then till now).

Is this symptom still reproducible in 8.10?

[peruron (peruron)]

Sorry for the late response. Happened in 8.10 as well.

it's so easy to laugh, it's so easy to hate, it takes strength to be gentle

I confirm the issue. It is exists in 7.10, 8.04, 8.10 . Found next: when I set processor speed to minimum in BIOS and disable multi-core, the notebook can work some days without halting. If processor speed is maximum and multi-core is enabled, it can halt in few minutes after booting.

I happen randomly. I experience the most serious one, 4 crash in half an hour. After that, when i login, Gnome show a black wall paper, and a pop up written, the gnome-power-manager is not configure properly......
then i have to reset .gnome configuration file by delete it. I have do a searching, it is related to Xorg.
By the way, i am using 8.10 64bit, t8100 processor, intel gma900.

Problem still happens with same original laptop and Ubuntu 9.04, 32 bit.
And it is random.

BTW, the problem is present in openSuse 10.3 and not present in ZenWalk 5.4/6.0. So, now I use ZenWalk on my laptop.
