Hi all,
I asked on #kernelnewbies what I should do with this and was told to check the
mailing list archive at http://marc.theaimsgroup.com/ - which I've done.
The following was produced during boot. I _looks_ like it was during a
modprobe, but I'm not entirely sure what - it could be that binfmt_misc but I
couldn't find any docs in the tree for BUG() tracebacks (and I probably
wouldn't have understood the source).
I'm not subscribed to the list: if anyone wants more info, drop me private
mail and I'll see what I can do.
Hope this helps,
Thanks,
-- Peter

Try this. I just sent it to Linus.
