It is actually failing in rmmod bttv, not rmmod videodev. videodev
shows up in the ksymoops decode because the bttv symbols have been
removed by the time the oops occurred. You need the values of
/proc/ksyms and /proc/modules from _before_ rmmod bttv was issued. man
insmod and read the section "KSYMOOPS ASSISTANCE", in particular
/var/log/ksymoops. Once you have /var/log/ksymoops setup, reproduce
the bug using
lsmod | awk '{print $1}' | xargs -l1 -t rmmod
When it fails, tell ksymoops to use the saved ksyms and modules in
/var/log/ksymoops from just before rmmod bttv. modules.xxx should
contain bttv and videodev but not tuner.
Send the clean decode to l-k, not to me.
