Yourself and others on another thread eventually recommended turning off TSO and what not. I never had a chance to thoroughly test this solution on this particular hardware because we had already switched to a different set of interfaces (on-motherboard bge(4)). We also had that ALTQ problem popup on em which I'm sure you remember, which prevented me from going back to the em interfaces for a while. After solving the ALTQ problem by going back to the 7.2-RELEASE driver, I thought it would be OK to switch this particular hardware back to using the em interfaces in production. (we were also experiencing kernel panics due to some bge(4) issue a few times a week). I had assumed, incorrectly, that because we were using the em(4) driver from 7.2-RELEASE, there would be no more "hanging" problem. I've also tried the latest CURRENT em(4) driver. So I am pretty sure I have experienced this problem under 8.0-RELEASE, 8.0-RELEASE w/ em(4) driver from 7.2, and 8.0-RELEASE w/ em(4) driver from CVS HEAD.
