Sorry to burst your bubble, but it just happened to me on a 7.0-BETA1
machine running 6.5.3. This machine (Supermicro P4SC8 board) had been
running without problems for almost a year previously.

It's still happening often on a 6.2-STABLE machine (as previously
reported).

Was doing around 40Mbit/sec of Rsync traffic at the time. Again, em0
shares an interrupt (this time with atapci, not uhci)
