you have some problems with your system clock:
Quote:make[2]: warning: Clock skew detected. Your build may be incomplete.
make[2]: Warning: File `/usr/include/locale.h' has modification time 7e+06 s in the future
fix that (i.e. make sure your system clock is correct and especially does not "jump"), then start all over again with extracting and patching the kernel source. you might want to save the kernel config (i.e. the file .config in the kernel source directory) and put it into the new kernel configuration directory. then the configuration should already be correct, but check a few options.

Hi again.
Done everything you said. I changed my system date (it was wrong), make clean all, re-downloaded everything, etc etc etc.
and im having this problem now:

Extra information:
im using trying to compile linux-2.6.26.8
Also, i tryed with 2.6.33.6 and i could make it compile, BUT, when i restarted server with new kernel, it give me a Kernel panic, so i had to go back to the default kernel.

you have either mixed versions (make sure your patch and your kernel sources have exactly the same version) or you have found a bug in some rarely used driver or so. try disabling everything that has (EXPERIMENTAL) in its name.

i have downloaded kernel + patch directly from your HOWTO tutorial links, so i dont thing that is the problem.
I will try by disabling everything that is optional.
btw, an offtopic question:
I have read in he "100hz better results" topic that its better to have Preemption set to disabled... Do you recommend that?
