Got an paypal account.
I think for quite some time to get an paypal account. Today I got one.
So if people like to donate money for my work in open source projects, they can do it via paypal now.
To make this clear, the preferred way to help open source projects is to write code, documentation, answer questions on maillinglist, etc. But if you don't have the skills, writing documentation should not be a problem at all, or time, donating money or hardware is also fine.
Just a short sidenote if you like to donate money for OpenEZX this way. This is a personal account, means you donate money to me and not to the OpenEZX project in general. If you like to donate for the OpenEZX project in general, get in contact with me and i see what we can do.
I will maintain a list with the donations I got. As you can see I already get one danation via paypal. Thanks goes to http://www.giantshoulderinc.com/.

Fighting with the new irq handling in 2.6.18 and our pcap demux handler
Antonio has started the port to 2.6.18. To get this ready, we need to change our
irq handling a bit. This is what i tried the last night.
I have never done irq handling before, not even think about it to much. Working with such code in the kernel is hard for me. But somebody has to do it, while Harald is busy. :)

First kernel patches applied for main.
Today patches I wrote were applied to linux-acpi-2.6.git
and will hopefully go into linus tree and 2.6.19.
It's the first time I submit patches for the kernel. Nothing really interesting, but a nice feeling anyway.

ipw2200 detected wrong geography problem.
I use the ipw2200 driver for my ipw2915 a/b/g wirless lan card. Normally I'm
total fine with this card. Active maintained driver inside the main kernel,
support for WPA, etc. But on the Linux-Kongress 2006 I run into
some trouble with Accesspoints on channel 13. I was able to find the ap during a
scan with 'iwlist scan', but not to connect to him. Searching for the
problem gives me an interesting notice in dmesg:
Hans-Joachim Baader and Felix von Leitner run into the same problem. So let us take a look what is happening here.
First of all the geography code is stored inside the eeprom of the wlan card. The driver only maps the code to an allowed channel list. This brings us to the point why there are wrong geography code for germany inside the eeprom. And the conclusion is, hardware vendors are stupid. :(
Some companies, I know from Acer and Packard Bell, have wrong geo codes inside the eeprom. I guess it's for a 'easily' handling of notebooks for different countries. At least Acer is not interested to fix this. Idiots. One more reason for never buying a Acer notebook. (Yes, I know you can run into the same trouble if you change the wlan card in your notebook. Exactly my problem.)
But there are two ways out of this problem. First, you can fit the mapping from geo code to channel list in the driver to your needs. This is pretty easy, but you need to patch your driver for every new kernel. The other possibility is to change the geo code inside the eeprom. This is a bit more risk, but you change the problem on the root. Andreas Oberritter has written a patch and a nice description how to do this. Good luck.
Have fun
ipw2200: Detected geography ZZA (11 802.11bg channels, 13 802.11a channels)I'm only allowed to connect to channel 1-11 in b/g band with this geography code. As i'm in germany here, i'm allowed to connect to channel 1 to 13. :(

Linux Kongress 2006
Some days ago i attended the Linux-Kongress 2006. The event
was well organized and had a lot well known speakers. Ted Tso, Alan Cox, Marcel
Holtmann, Jeff Dike and Felix von Leitner are just some of them.
Especially the social event was pretty nice. I meet Christian Daniel, Thomas Kleffel and Matthias Kleffel first time in reallife. Unfortunately they have to leave Nuernberg after the social event again to prepare for work and exams. If everything wents fine they prepare some neat DVB-T stuff for 23C3. Stay tunded. ;)
After social event officially ended, i went, together with Marcel Holtmann, Thomas Gleixner and some SuSE guys, into another pub for some more beer. It was fun, but only 4 hours sleep plus one or two beer to much don't gave me the best start for another conference day.
