Hello Subhro,

I have nothing to add besides a "me too." 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

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. Life is either
a daring adventure, or nothing.
