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

Here is my dump information:

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

hello denk,
I am sorry i have not described clear.
We use HardHat CDK1.2's cross compile.
We use firmware from pSOS's, and just move kernel's
image from flash into sdram then jump to it.
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
here is ps's output:
# ps -e
PID TTY TIME CMD
1 ? 00:00:15 init
2 ? 00:00:00 keventd
3 ? 00:00:02 kswapd //here sometimes will
change to <defunct>
4 ? 00:00:00 kreclaimd
5 ? 00:00:00 bdflush
6 ? 00:00:01 kupdated
12 ? 00:00:00 sh
14 ? 00:00:00 inetd
77 ? 01:23:54 video_start //this is our
server application
80 ? 00:00:00 ps
and i don't know how to decode backtrace?
thanks.
