Hi All:

    I am interested in CLOCK-Pro in linux.

    I use Riel's patch in linux-2.6.12 and linux-2.6.12.6, but both can 
not apply. (it will
generate some *.rej files). So, I adjust a bit offset of some lines. It 
do not report any
reject result, and compile sucessfully (2.6.12.6).
   
    When boot with this new kernel, kernel often pop oops message. the 
Oops like this:

I think , I perhaps lost something in patch. but I can not find it.

These attachmentes are the patch that I changed and two dmesg files.

Any idea on it? or which version kernel can apply original CLOCK-Pro patch?

Thank in advanced.
