We have three Tyan GT20 (2865) NForce4 based machines with a single-
core Opteron and 2 GB of RAM, running stable i386 from two days ago.
(dmesg and kernconf attached.)
Often, but not always, we get the following panic when logging out on
the serial console, or when rebooting the system.
Another machine with the same mainboard does not exhibit this behavior.
