Hi, I have encountered the same mtag panic Craig had with VIMAGE + PF and have reported this in a PR 182964: http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/182964 Here are two possible solutions I would like to discuss, both make the panic go away: 1.) de-virtualize the variable as Marco suggested, this solution is a more intrusive change to pf.c http://people.freebsd.org/~mm/patches/pf_mtag.patch 2.) add vnet context to struct m_tag, this is less intrusive to pf.c and the uma zone remains virtualized: http://people.freebsd.org/~mm/patches/pf_mtag.2.patch Which of the approaches should we take or is this to be solved in a completely different way? Anyway, after patching I have fired another panic, this time caused by missing vnet context in the pf overload task queue. I have discussed a solution for this one with Gleb and he committed it in r256587: http://svnweb.freebsd.org/base?view=revision&revision=256587 With both patches applied my VIMAGE + PF system runs stable. Thanks, mmhome | help
