The results for linuxthreads when using the uclibc-ng testsuite are not so bad. With NPTL we have right now 99 errors. 
The problem is that I took the code from the old uclibc fork and merged the glibc nptl stuff. So with Stafford the first time an or1k expert is looking into it.
It took me very long to start with the runtime testing as I had a non working kernel config for a long time.

I think this was the base for my try to integrate NPTL support.

I hope we can identify the open issues and make the port a well working port like Arm, nds32, Mips, Xtensa and Arc.
