1. $ ls
   arch     crypto         include  kernel       mm              scripts
   block    Documentation  init     lib          net             security
   COPYING  drivers        ipc      MAINTAINERS  README          sound
   CREDITS  fs             Kbuild   Makefile     REPORTING-BUGS  usr

   The maintainer of the r8169 driver is listed in the MAINTAINERS file.

2. Disabling CONFIG_NET_ETHERNET is a bad idea. Don't do that.

3. See tethereal -w or tcpdump on the adequate interface to save a
   traffic dump.

4. Are you using a binary module for your video adapter ?

5. How does the 2.6.20 version of the r8169 driver behave ?

6. You may setup a cron to monitor an ethtool dump of the register of
   the 8169 at regular interval. ifconfig and /proc/interrupts could
   exhibit some unusual drift as time passes on too.

7. A dmesg would be welcome.

8. Please open a PR at bugzilla.kernel.org.

CONFIG_MAGIC_SYSRQ is set. Check that the magic sysrq is not disabled at
runtime through /etc/sysctl.conf. See Documentation/sysrq.txt for details.

Please keep Steve French in the loop.
