Linux crashed again – and I hit the reset button at 5:30 am on my way out of the door for two days.
Unfortunately, Gentoo seems to be loading modules in a weird way (that is, not in the order in which they are listed in the modules.autoload files, which is how it used to be), because the network interface cards got switched again. So despite the server actually coming back up at 5:35, I wasn’t able to replug the network cables until I got back. Sorry all for the inconvenience.
I am actually considering dumping the entire setup – it’s no fun running an ill-behaved server. I’ve upgraded to the latest kernel and VServer 2.1.0 final – lets see if that is able to stay alive for more than a few days.
