Bug#637122: general: Realtek RTL8111 with r8169 module causes kernel panic on large packets
Thanks Ben. My first bug report, so excuse the lack of info. :-)
This is a command you can run from the Windows command prompt to cause
the
crash (I believe the -l switch is equivilent to -s on unix, but I think
windows might handle ICMP pings a little different too)
ping -l 8146 serverhostname

This is most of the kernel panic. It scrolls away awfully fast and I had
to
change the resolution and font the screen was running just to get this
much.
The things I do for FOSS. :) I apologize that this is the best I can do.
I hope you guys can piece the images together.

Here's some additional info about my interfaces. I believe the MTU
setting
of the Realtek card is important to making this crash happen but I
haven't
tested too thoroughly.
eth0 is the Realtek r8169, lan is the bridge that eth0 is in.
# ifconfig lan

Which package version do you have installed?
(Run 'dpkg -s 'linux-image-2.6.32-5-686'.)
Also, you must send the panic messages. Use a serial console or
digital camera to capture them.
Ben.
