CC'ing Jack Vogel of Intel, who is currently re-working portions of the em(4) driver. I think taskq issue might be the thing he's fixing and thus might have a workaround for you. But we're going to need to know exactly what em(4) model you have. Please provide "dmesg" output relevant to em0, and also "pciconf -lvc" output for the em0@<xxx> device. -- | Jeremy Chadwick j...@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
