| |
Repeatedly inserting and removing the modules in the ipv4 directory under heavy networking load seems to cause an Aiee very quickly. It filled more than a screen and didn't get written out to disk, I do have the dump from an Oops I was able to provoke in 2.3.99-pre2 under similar conditions but which much more effort, if this is any use.
The exact procedure I used to provoke this was:
On some remote machine which can ssh to the machine running 2.3.99-pre3 [coconut] using RSA auth and no passphrase:
while true ; do ssh coconut cat /vmlinuz >/dev/null </dev/null ; done & [repeat a few times]
On coconut:
cd /lib/modules/2.3.99-pre3 ls | cut -f 1 -d'.' > ~/ipv4.modules [edit ~/ipv4.modules to remove ipchains and ipfwadm]
while true ; do for d in `cat ~/ipv4.modules` ; do modprobe -k $d ; done ; rmmod -r `cat ~/ipv4.modules` ; done
Cheers,
Ganesh
