Hi all, I found the following problems compiling modules for vmware and cisco-vpn for 2.6.19-1.2895.fc6 : 1) vmware uses somewhere CHECKSUM_HW. This used to be defined in /usr/src/kernels/2.6.19-1.2895.fc6-i686/include/linux/skbuff.h. I had to add "#define CHECKSUM_HW 1". 2) ciscovpn : in interceptor.c the function skb_checksum_help is called with 2 arguments. This has been changed to 1. leaving out the second argument did help. I do not like this at all. I like "backwards-compatibility" very very much, so that you will not break "old" code.
