Re: Why system panic after sometimes?

In message [ref] you wrote:

This question has bothered me,I use linux-2.4.4 (
downloaded from denx.de and porting to our borad
MPC850+4Mflash+32Mram+USB).We run a server application

Which version of cross tools are you using?

What firmware is used to initialize the board?

Which device drivers are used? USB???

in borad,but after sometimes such as about a day or
even several hours ,system will panic. I check our
program, i think there are no memory leak(or it will
panic in same time) and other fatal error.
Here is my dump information:

Did you ever try to decode this backtrace? What's that C0128750 there?
