SubjectOopsen everywhere in open_namei, kernel 2.4.3
Right after a boot, I got 5 oopsen within about 8 minutes.  There are
only two unique ones, which are attached. Each one occured at least
twice. Someone know what's going on?

Freedom is the freedom to say that two plus two equals four.
ksymoops 2.3.4 on i586 2.4.3. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.3/ (default)
-m /boot/System.map-2.4.3 (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.
