Palmen [20050410 11:16]: > So I assume there is a problem in the appletalk code, but I didn't try > reproducing that on other systems so far. I've now tested this issue on a vanilla 2.6.11.7 kernel. I only applied my own patch from the previous post so that I am able to shut down the computer cleanly. So I did the following: - boot 2.6.11.7 - create a tap device with 'openvpn --mktun --dev tap0' - create /etc/netatalk/atalkd.conf with a single line 'tap0' - launch atalkd, wait. - stop atalkd. - destroy tap device with 'openvpn --rmtun --dev tap0' refcnt was -256, very strange. Would you consider my patch harmful? I intend using it for now, because otherwise, my system won't shut down cleanly any more...
