a possible bug in netfilter

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

Sometimes my system panics and below you can find the information I was able to catch via netconsole.

LFS-based system, kernel 3.3.1, xtables-addons 1.41

If I can do something to help you with debug/troubleshooting please let me know.

Thank you in advance,
Serge
