Oops 2.4.9

[Adam Huffman]

Overnight I had a couple of oopsen on my Athlon box, now I've had some
more when running rpm and ksymoops.

System is RedHat 7.1, Athlon 800, Abit KA7-100 m/b.

The 5th August CVS snapshot of the ieee1394 code had been applied (and
worked without incident for a month or so).

First, the one just now, when running rpm:

ksymoops 2.4.3 on i686 2.4.9.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.9/ (default)
     -m /boot/System.map-2.4.9 (specified)
