[Sparc] Oops in 2.4.17-rc2

[Sparc] Oops in 2.4.17-rc2

[Alex Buell]

I've just had my SS4 gateway blow up in my face with an OOPS. I had to
write down the Oops on paper so I think the resulting ksymoops may be a
bit wonky, but hope this will be of use to someone.

ksymoops 2.4.3 on sparc 2.4.17-rc2.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.17-rc2/ (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.
