computer randomly freezes
Whenever I fire up my laptop, I have to be careful, because of the above problem. Now, ever since I have got Direct Rendering with my ProSavage chipset working, I've had that kind of problem with my laptop, since 2.6.11 to 2.6.15. Since then, I've switched from Gentoo to Ubuntu, and I can tell you the problem hasn't changed at all.
As I run the kernels over and over again, I think the freezes become more frequent. Then, I get frustrated and recompile my kernel (without issuing a make clean and mad optimization flags, it doesn't matter either way), and when I do that, the freezes diminish. Then after I run the kernel a lot of times, the freezes become more frequent. At least, that is my feeling for what is happening here.
I run X11R7.
Established: The freezes have nothing to do with kernel Savage DRM, or AGPGART. This is because I compiled another kernel without those options, and it still freezes.
Established: The freezes do not occur when X is not running, although when X is running and I am in Ctrl-Alt-F1, for example, it will still freeze after some time.
FOOD FOR THOUGHT: It used to freeze after some time even when X was not running in Gentoo, even when I wasn't even logged in. However, I don't think I have experienced that with Ubuntu. Perhaps it is because no console app in my Ubuntu system is linked against X, unlike my Gentoo version of links, which wouldn't run if X was not installed.
Established: The system usually freezes when there is heavy disk activity, for instance, running dpkg --configure -a after a botched install. Tried compiling my VIA chip driver as a module. Did Not Help. Will not remove my VIA chip support from the kernel.
Established: I don't think the system crashed when I used the vesa driver for X.
I hope you guys will help me out and give me further places from which to troubleshoot, because once the laptop freezes I am unable to quote any system logs or kernel messages. So sorry, no informative messages here.
