The compat-drivers I'm quoting is 3.7.6.1-stable and from the daily build tars (2.20.13). GCC version is 4.2.3 C-D compiles, but as noted with a tonne of warnings. We have several servers with specific purposes running 2.6.24 kernels and I decided to try a C-D on them. I guess the question now is, do we drop support for c-wireless/drivers for 2.6.24 - 2.6.29(?) and bump the minimum kernel to a 2.6.30?

Is 2.6.24 still supported? What version of compat-drivers are you using? What version of gcc are your using? Some parts of compat-drivers are still compiling against kernel 2.6.24, but I would not recommend using a so old kernel. I haven't done run time testes with 2.6.24 for a long time. > Also, there was an issue with 50-compat_firmware.rules. Ubuntu 8.04 looks for it at /lib/udev/rules.d/ which gave me severe problems with firmware loading and system freezes. I had to copy/symlink 50-compat_firmware.rules from /lib/udev/rules.d/ to /etc/udev/rules.d/. Could you provide a patch for this, I do not have a ubuntu 8.04 installation any more, this is pretty old. > Warning log (partial). It compiles, but warnings galore.

There are some other warnings with gcc 4.7 therefor I used "export KCFLAGS="-Wno-unused-but-set-variable"" with these old kernels, newer kernel versions already do this in the main Makefile. Hauke
