Reading a kernel dump

Postby atomize » Fri Mar 05, 2010 5:37 am

I am working on a robot which crashes after running for a very short while. I am trying to decipher what the error message is trying to say.

The error message is as follows:

Shutdown[0,0] S/C/F=11/4/2 C/D=F00129b6/f0046ec0 state(d0)=now lock exit
[0]PID-TID=1-1? P/T FL=00019001/08800000 "/86/boot/sys/procnto"
[0]ASPACE PID=4101 PF=00001010 "poc/booy/io-net"
x86 context[feff4f74]:
...
instruction[f000d26c]:
...
stack[feff4fa0]:
...

-------------------------------------------------------------------------------

In S/C/F=11/4/2, 11 means 'segmentation violation', 4 means 'general protection' and 3 means 'privileged instruction'.

I am not sure what the above means. Can someone shed some light???

Thanks.

that means io-net did a SIGSEGV and most probably inside an interrupt routine. Either it's a hardware problem or a bug in the network driver.
