Several of my testers are being blocked by this as well. Instead of having a log2_compat.h, wouldn't it be easier to have an rtctimer.patch that reverts to prior rtctimer.c behaviour? What was the purpose of this patch? The l"is_power_of_2 function isn't even in a release kernel (it will be in 2.6.21).

Here is a patch against the 1.0.14rc3 tarball. It will need more refinement for HG, but it works on my Mandriva 2007 kernels.

Hi:

I am getting the same error trying to compile either the 1.0.14rc3 or the Mercury versions of the driver.

I get the following in both:

====================================

The header file, log2_compat.h is not in the rc2 release; I have no problems compiling rc2.

Does this mean that I have to be up to a certain rev on the kernel?

I am running red flag with the 2.6.17.13 kernel.

Thanks
