Can I ask a stupid question? I see multiple references to r8169 in the 
log. Is you NIC by any chance an RTL8111/8168/8411? Do an "lspci -k | 
grep Eth -A 3". If it is, I've seen it give so many different issues 
when it is used with the r8169 driver, but it works really well with the 
r8168 driver. ElRepo (http://elrepo.org/tiki/tiki-index.php) maintain a 
kmod compatible version. I am wondering if this may also be solved by 
using the better driver.
