Intel 82567LF network

I'm currently trying to get debian installed on this litty fellow. The network chip is only supported bei 2.6.28+ kernels, so I can't use any of the standard debian/fai kernels. I've tried the current kernel from the debian kernel development repository in the the trunk, but this only results in a load of stacktraces and finally a kernel panic. I have no idea so far, what the cause of the kernel panic is. A quick try with the current ubuntu live-cd reveals, that it should be working somehow. The stacktrace however keeps filling the log files at a very fast pace. Within 5 minutes the ubuntu live-system dies because the ramdisk is filled up by /var/log/messages with entries like this one:

Since that fills up the space avaibable, my guess would be, that those messages fill up the initial ram disk of the netboot environment via FAI and thereby kills it before beeing able to mount the real root.

wiki2wiki website launch

I've managed to finish the wiki2wiki website. Although the program itself is not yet finished the website hopefully attracts some more developers towards it. I guess it'll take some time till the website makes its way into google. Maybe someone will find it and want to join the development ;)

firebug

I just recently discovered firebug . It proves quite usefull especially when you have to do a lot of web programming. Live editing of css styles is my favorite right now *G. Semantik annontation combined with javascript in perl... quite a funny project I'm working on right now, but more on that later...
