Hi, About Kernel 2.6.6 with NPTL on Debian.
 

Hi, all
I compile kernel-source 2.6.6 on Debian, but it seems non NPTL support.
I compile kernel-source-2.6.6, glibc6 2.3.2-ds1-16, glibc-i686 2.3.2-ds1-16 glibc6-dev-2.3.2-ds1-16
On a machine the NPTL works fine!
But on another machine, the same kernel(I tried same kernel config and same binary kernel iamge) and libc, the NPTL NOT work!
I can not find any diff between two machine!
How can I make sure one system already support NPTL? 3ks!
I use j2sdk 1.4.2, run rmiregistry to test this feature, one machine have 1 process and 8 threads, one machine have 8 process.
I also use OpenLDAP compiled with thread support, have some issue on these two machine.
Any suggestion?

I think this is the libc proplem.
I downgrade libc6 and all related packages from 2.3.2-ds1-16 to 2.3.2-ds1-13, and the NPTL worked fine!

I think I have a big error in this issue.
I reinstalled the server and traced all package install, update, and I found the NPTL has been disabled while I install x-window-system from unstable, when I install it from stable, all be fine!
