It seems possible that these commands (above) are flushing the kernel
log buffer to disk (/var/log/messages e.g.), so that they don't need
to be saved by kmsgdump. Have you looked in the kernel message file
for them?

You are right, the oops indeed makes it to the disk in that case, thanks!
Here follows a nice oops. Probably very easy to reproduce to any speedtouch owner by launching /etc/init.d/hotplug stop while modem_run is still running...
