I ended up replacing my em0 with an fxp0 and all of my networking issues (watchdog timeouts, link dropping/reconnection, etc.) disappeared. This may have been flaky hardware. Do you have another NIC you can try with? Thanks, Josh -- Josh Tolbert hemi@puresimplicity.net || http://www.puresimplicity.net/~hemi/ Security is mostly a superstition. It does not exist in nature, nor do the children of men as a whole experience it. Avoiding danger is no safer in the long run than outright exposure.
