>Description:
During heavy, sustained network activity, the fxp driver reports a "device timeout" error, and the interface basically "goes away". Existing connections ot the machine (that route through that interface) hang for a period of several seconds to less than a minute, at which point it comes back up.
A look back through my messages logs of old shows that this did happen once or twice under 4.5-RELEASE, though I don't recall actually seeing application troubles during day-to-day work. It may have been a problem before then, too. But, under 4.6-RELEASE, it happens frequently (every two or three attempts to do large file transfers), and I can see the effects of it quite clearly. So whle the phenomenon may not be new,
the upgrade to 4.6 has drastically increased the frequency of occurance.
Note that this is a dual-proc system. Here's dmesg from my most recent boot:

Here's the error as it appears in the logs:
fxp2: device timeout
>How-To-Repeat:
I have been most successful repeating this problem using Samba to transfer large data files or data file sets to a Windows PC. Anywhere from 100 Mb to 400 Mb into the transfers, the connection drops and the BSD system reports a device timeout.
I have been able to reproduce this both on a dual Intel network adapter (either an 82558 or an 82559, I don't remember which) as well as on the on-board LAN (an Intel 82559 on an L440GX+ motherboard).
