kernel: Oops: 0000

Postby jodo1931 » Wed Nov 07, 2012 11:15 am

Ever since I have started using SKYPE to communicate to my Great Granddaughter's
family, I started experiencing Kernel errors. The router still works but seems to
be sluggish after the error has occurred. My guess is memory overload but how to
circumvent it escapes me. Here is info from log...they are all identical:

Oct 23 12:20:27 - kernel: Unable to handle kernel paging request at virtual address d3a801b2
Oct 23 12:20:27 - kernel: current->tss.cr3 = 00101000, %cr3 = 00101000
Oct 23 12:20:27 - kernel: *pde = 00000000
Oct 23 12:20:27 - kernel: Oops: 0000
Oct 23 12:20:27 - kernel: CPU: 0

System listing attached.

Any suggestion is appreciated.

There are some things to try, first install the 3x90x.gz driver in the /boot/drv/ directory and reboot the system. It is located in the 'modules-2.0.40/net/' directory of the original download. This is the actual 3Com driver for your card and usually works just a slight amount better. Although I am not seeing any type of errors on your cards, it still may help under load. You might also consider some faster cards, because if you start getting close to the limit of a network card it can cause some unexpected results in a router environment.

Also shut down the system and reset the memory. Occasionally on an older system the pins get a small amount of corrosion and can cause various symptoms.

Check and make sure the CPU cooler is running ok and the CPU cooler is clean. A CPU running a small amount hot can also cause various issues. This also includes the power supply fan.

Change the kernel from the stock kernel to one of the 686 kernels. The stock kernel is made to run on 386 and up systems. This means that everything that is built into the CPU is done with software rather than using any of the built in hardware a Pentium class CPU has. 686 kernels will enable the hardware and make the system run much faster.

Check your hard drive for any type of error. Run scandisk on it to ensure there are no issues. I strongly recommend that everyone use the ext2 file system for FREESCO because of various problems the system can not fix on it's own. Which is VERY easy to install from a running floppy in the package menu.

As you can guess, a kernel "Ooops" can be caused from just about anything. :?
If you are afraid that you might make a mistake. The chances are high that you will never learn anything.
