If you see watchdog timeout errors on your console, shared interrupt
would be culprit.
For msk(4) set hw.msk.legacy_intr="1" in loader.conf or use kenv(1)
to set it before loading msk(4) kernel module.
For nfe(4) you can switch to polling(4).
I have some msk troubles too. On my laptop (acer travelmate 2483wxmi)
under heavy cpu & network load msk periodically stops working for few
minutes.
