[1.] One line summary of the problem:    
cat /proc/ioports seg faults

[2.] Full description of the problem/report:
Upgraded from 2.4.10 to 2.4.11, during troubleshooting a usb problem, I was
cat-ing /proc/interrupts and /proc/ioports. The last cat to /proc/ioports seg
faulted and syslog says this:

[5.] Output of Oops.. message (if applicable) with symbolic information 
     resolved (see Documentation/oops-tracing.txt)
ksymoops 2.3.4 on i686 2.4.11.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.11/ (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.
