That's bad, right?

I guess I'll have to reboot it when I get anywhere near it. In the mean time, I've had to shut down its buildd, since not running kswapd is wreaking havoc with the load on jazz. And while I'm at it, might try to install 2.6 on the box, too, see whether that works yet.

Only that has a different set of issues; it doesn't seem to be possible to generate initrd images for 2.6 kernels while you're running 2.2. And I'm not compiling my own kernels; Debian's kernels are just fine. If I can get them to work. Suggestions, anyone?
