Just to be clear, has it been established that the problem only occurs
when em is sharing an interrupt? I have a lot of production machines
using the PDSMi board, which is one of the boards that the problem was
noticed on, however i do not share any irqs, i always disable USB in the
BIOS.
# vmstat -i
interrupt total rate
irq16: em0 13001181 7
