First of all, it's my first post here ...
Thanks to everybody that made FreeBSD possible.

Sorry to say, I think that 'me too'
My re0 comes with the motherboard, a Gigabyte GA-MA69G-S3H (AMD 690G
I've tried yesterday with RELENG_7_0 (RC3) and RELENG_7, same behavior
on both. I've returned to RELENG_7_0 and plug an em0 but, in my case,
the same behavior happens. I left the box by night compiling CURRENT and
this morning I've run my 'stress tests' (once again with re0) ... the
box break to gdb as far I remember (too sleepy, sorry). Well, at least
no garbage over the link BD.
The fastest method I found to reproduce the problem is receive a
compresed tar (with good compression ratio) over the network (using nc,
100 Mbps fdx), pipe through tar that decompress and write it on disk (a
lot of MB/s and tps looking at 'systat -vm'). The source tar file is
about 5Gb and link always fails before EOF :|.
The em0 is brand new so no idea if it works right. It would be the first
one that fail to me (great stuff intel ;) ... I'm pretty confident about
the switch and allow setting flow control, duplex negotiation, dot1q and
I'll be glad to test whatever you suggest on that box.
