Subject:  Kernel panic with 2.6.24.4 and L7filter patch


Hi everyone, I got this a kernel panic with a 2.6.24.4 patched with 
netfilter-layer7 (http://l7-filter.sourceforge.net/)
This is not a machine I directly administer and for now I don't know
how to reproduce the panic, but if necessary I may investigate more.
I'll submit this to the l7-filter-users ML but I was wondering if this
a known bug unrelated to l7-filter.
