Subject2.2.9 oops

Encountered this oops several times with 2.2.x.
Usually it appears 2 to 3 days after booting, in which after about a few
hours/minutes the system panics...

Hope that someone can debug this coz it's on my production machine :(

below is an ouput of ksymoops together with some info on

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.
