Hi All,
Ok, here is the oops that I captured via a serial console when my
machine locked up while copying a file to my external usb 2.0 hard drive
enclosure. This is with the latest usb drivers for the 2.4 kernel.
ksymoops 2.4.5 on i686 2.4.19-16mdk-debug. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.19-16mdk-debug/ (default)
-m /boot/System.map-2.4.19-16mdk-debug (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.
Warning (compare_maps): mismatch on symbol __nvsym03120 , NVdriver says
c0de3920, /lib/modules/2.4.19-16mdk-debug/kernel/drivers/video/NVdriver says
c0ddc1c0. Ignoring
/lib/modules/2.4.19-16mdk-debug/kernel/drivers/video/NVdriver entry
