Re: Why system panic after sometimes?

Hello,

in message [ref] you wrote:

I am sorry i have not described clear.
We use HardHat CDK1.2's cross compile.

This is pretty old, but should work for this purpose.

We have not use USB driver yet, I have writed a driver
for a MPEGI coder chip (operate it via data and
address bus).I think my driver (just handle interrupts
from chip) is safe and will not affect kernel

Well, I think the kernel version you are using  is  very  stable,  so
maybe it _is_ a problem in your driver?

and i don't know how to decode backtrace?

See  Documentation/oops-tracing.txt  in  youir  LInux  kernel  source
directory; alternatively, look up the addresses / symbols manually in
the Systems.map file in your kernel directory.
