Thanks for the extensive testing to narrow down the problem introduction point! It seems from your results that the commit to if_fxp.c is the most likely candidate for causing the crashes, since setting mcl_pool_max to 0 should have undone the effects of the uipc_mbuf.c changes. Could you try using the latest 4.6-STABLE source, but with the old version of if_fxp.c? Grab it from cvsweb at http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/src/sys/dev/fxp/if_fxp.c?rev=1.110.2.23&content-type=text/plain&only_with_tag=RELENG_4 if you don't have a copy saved already. > Was this helpfull? Very much so! Thanks a lot for going to the trouble of trying so many different dates. It's time-consuming work, but nothing beats this kind of information when tracking down what is causing crashes.
