I’m also seeing breakage with the em0 device; this isn’t a kernel hang, it is a failure to move data after about 10-15 minutes. The symptom is that my WAN ethernet no longer moves traffic, no pings, nothing. Booting looks normal:

em0: <Intel(R) PRO/1000 Network Connection 7.4.2> port 0x30c0-0x30df mem 0x50300000-0x5031ffff,0x50324000-0x50324fff irq 20 at device 25.0 on pci0
em0: Using an MSI interrupt
em0: Ethernet address: 00:16:76:d3:e1:5b
em0: netmap queues/slots: TX 1/1024, RX 1/1024

Fixing it is as easy as …

# ifconfig em0 down ; service ipfw restart ; ifconfig em0 up

:-)

I’m running CURRENT, r287538. This last worked of me a month or so ago at my previous build.
