I use Debian Squeeze 6.0.3, my kernel is : Linux SRV-01 2.6.32-5-amd64 #1 SMP Mon Oct 3 03:59:20 UTC 2011 x86_64 GNU/Linux Currently I'm using the r8168 driver. I tested the new driver r8169 compiling a kernel 3.1rc4 and everything works perfectly: https://launchpadlibrarian.net/83450424/Capture-Linux-x86_64%203.1.0-rc4%20Kernel%20Configuration.png It's the same problem on launchpad, it's just that I never reported a bug here sorry.
