Have anyone tried to get 2.6.19.x to work on Nios2 yet ?

I've done a port which is mostly OK, but I have experienced a couple of issues not present in 2.6.18:

* /proc/<pid>/cmdline is empty for all processes. This could possibly be releated to the new kernel_execve call (used to start init).

* Top (from busybox) is using up to 100% CPU. Probably some /proc problems (top monitors /proc/stat).
