I did it, and now have the oops decoded.
To who must i send it, besides this list and Alan?

Attached, there are two oops decoded, these oops occours when i try to enable 
DMA and burn with my burner only when connected to a PCI IDE controller
(others also reports DMA data corruption on similar configuration)

ksymoops 2.4.5 on i686 2.4.20.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.20/ (default)
     -m /usr/src/linux/System.map (default)

Warning: 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.
