Hello,

here are the requested informations
Kernelversion is 2.6.24
ramdisk_size=159844
Kernel and miniroot can be found in the following debian package:
http://download.uib.de/debian/dists/etch/opsi3.2/binary-i386/opsi-linux-bootimage_20080207-1_all.deb
The crash happens before the Kernel starts - while loading the miniroot.gz

I forgot to mention that it is not only a pxelinux.0 based problem: 
with isolinux we get the same situation (3.11 fails, 2.04 works)

Thanks
