Ubuntu suddenly reboot: a problem about Clocksource tsc unstable?
Hi all..
I've this configuration
I've already posted a similar problem (See my question :"NVIDIA crash&reboot.."), but now I've understand my real problem.
My configuration
Ubuntu 9.10 64 bit
Video: GeForce 8600GT
Monitor: ASUS LCD ACI VH226
Motherboard&CPU: Asus with AMD 64 Athlox X2
RAM: 2 Gb
Propretary drivers 185 installed by ubuntu menu
THE PROBLEM:
Sometimes (often when I use 3d application or "hard" applications) and doing antithing special, the system suddendly reboots without any explanation. In the kern.log I find: "Clocksource tsc unstable (delta = -116657500 ns)". So I've search in google and I've found that the problem is linked to frequency scaling of my CPU: so I've added to my menu.lst (grub) the line "clocksource=
After that, the system still crashes, but only after a time longer and when an application seems to question an "high charge" (es cairodock).
Now I'll try to disable ACPI cpu (frequency scaling) in BIOS.... but there is another way to solve this problem ?
Thanks
