kernel BUG at slab.c:1292

[Peter L Jones <peter@drealm.org.uk>]

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
