Possible stability issues with Debian AMD64--it has frequent updates with apt-get dist-upgrade
eth0 & eth1 on same interrupt (eth0 very low traffic though)
There are two drivers for the Broadcom ethernet adapters: tg3 and bcm5700(?). The tg3 driver is default with Fedora. The bcm5700 driver is released under the GPL by the manufacturer, but is not in the mainline kernel. It is also a bit old.
