I believe we had the same exact experience the other day when a dell pe2850
dropped off the network for two hours in the morning. I wasn't there at
the time, but a coworker said that after he touched the keyboard it
seemed to come back to life.
We decided to move to 6.2-PRERELEASE after that incident to see if would
help. So far, we haven't had another incident of that type, but it
hasn't been running for more than a few days with the changes. I also have
not had the chance to test the recent if_em merge.
Just to note, I have the usb controller disabled in the bios due to it
causing interrupt problems with the em NIC when I first installed
6.1-RELEASE as others have reported. I haven't tried turning it back on
to see if the problem remains. The apic is also enabled (SMP box). I
have not tried enabling DEVICE_POLLING.
