PROBLEM: <i386 2.4.22 OOPS running Mozilla>

[Albert Chin-A-Young]

NOTE: All output below is from the system after I rebooted it.

  1. i386 2.4.22 OOPS running Mozilla
  2. i386 2.4.22 OOPS running Mozilla
  3. kernel
  4. $ cat /proc/version
     Linux version 2.4.22 (china@slab) (gcc version 2.95.4 (Debian prerelease)) #1 Wed Aug 27 00:18:11 CDT 2003
  5. $ ksymoops < /tmp/a (/tmp/a contained Oops snippet from kern.log)
     ksymoops 2.4.9 on i686 2.4.22.  Options used
          -V (default)
          -k /proc/ksyms (default)
          -l /proc/modules (default)
          -o /lib/modules/2.4.22/ (default)
          -m /boot/System.map-2.4.22 (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.
