Subjectoops on continous file read.
Date
Hi,

When i am reading a huge video data
file ( 99 MB ) i am getting this oops on kernel
version 2.2.12-20. This is happening when i run
the app more than 4 times.

I am not able to analyse this oops.
Can any one help me.
Attached is the oops and the output of ksymoops.

Thanks in advance,

WARNING: This version of ksymoops is obsolete.
WARNING: The current version can be obtained from ftp://ftp.ocs.com.au/pub/ksymoops
Options used: -V (default)
-o /lib/modules/2.2.12-20/ (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-m /usr/src/linux/System.map (default)
-c 1 (default)

You did not tell me where to find symbol information. I will assume
that the log matches the kernel and modules that are running right now
and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
