Hi there, I am sending your a bunch(!) of logs I think all cast some light over what ever is wrong with my brand machine. Since I got it up running, it has been crashing now and then. It is an AMD T-Bird 900MHz (running at 100MHz x 9 -- not overclocked or begin tortured in similar ways), 256MB PC133 RAM, a IBM DeskStar IDE HD and an NVidia GeForce2MX-based graphics card (Hercules Prophet II to be specific). I use a binary version of XFree86 4.0.2 with an Nvidia driver. I use WindowMaker 0.61.0 as my window manager. The kernel is version 2.2.18. My old system is a P166 and it has not crashed for years. I do not run MS Windows, so yes, crashing does worry me alot! The first couple of times, the system crashed when I switched back and forth between X and console (Alt+Ctrl+F1 in X / Alt+F7 in console). The next few times it happened when I changed workspace from Blender3d (a 3D modelling and animation program using OpenGL) to a clean workspace. This lead me to think that it had something to do with either X 4.0.2 or the driver from NVidia (which is know to have some minor redraw-bugs). So far a "crash" means it locked up my machine completely; no keyboard, no mouse, frozen screen. (I am currently not in a network, so I cannot ping and see if the kernel has frozen completely). But yesterday (january 15 2001) it crashed my X and for the first time left me in console with an error message from the kernel: Unable to handle kernel NULL pointer dereference at virtual address 00000000 current->tss.cr3 = 0dea4000, %%cr3 = 0dea4000 *pde = 00000000 Oops: 0000 CPU: 0 My gpm was killed so I tried to switch to another terminal to restart gpm and cut'n'paste the output to a file, but then it froze completely -- again. Now I am no long sure that it's a problem related to X or the NVidia driver. I could also be hardware. But as said, the computer is brand new and I am not overclocking anything. I run a memtest86 on the machie this night for 13 hours straight with all tests enabled, but it found nothing. So, I send you the logs and kernel configuration in the hope that perhaps you can help me out.
