Can you try the following version?
This one compiles and links without problems.
The reason I want to use this patch is that I hear a high pitched noise [1] when running with 1000Hz and the processor is idle. With this patch I could use 1000Hz without any noise.
But I found some problems on my system:
- time does not run the correct speed, it was some minutes in future after I had compiled a new kernel
- pressing a key on the keyboard sometimes results in two or more characters, not only one
- mouse misses some events, e.g. clicks are not recognized (synaptics touchpad)
- using software suspend 2.1.8.10 I can suspend the system, but it hangs while resuming
Anyway, thanks for your great work! Let me know if you have new versions to test.
