Subjectprobably very irrelevant oops
Hi,

I built a fairly pathological kernel based on 2.4.17 with sched-O1-H7,
ext3-0.9.17, XFS, jfs-1.0.12 and Intel's e100. (Things are orthogonal
enough that they patch together easily :)

It boots fine (but not with devfs) and I can use all four journaled
filesystems together happily. So I thought I'd try two very stupid stress
tests.

find /lib/modules/2.4.17-expt/kernel/ -type f|while read i; do insmod $i; done
[Great. A few hundred modules load, no doubt some clashing with others.
However, lsmod seems to suggest we've overrun a buffer as the output
looks truncated (my find produced 597 lines, but lsmod only 300 or so)]

awk '{print $1}' /proc/modules|while read i; do rmmod $i; done
[BOOM. But I was asking for it.. the first three warnings are the modules
in my initrd]

ksymoops 2.4.1 on i686 2.4.17-expt. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.17-expt/ (default)
-m /boot/System.map-2.4.17-expt (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.
