!clrstack never reports anything

Question

I know I am dealing with a managed thread but I have never managed to get !clrstack to work. I always get:

0:000> !clrstack
OS Thread Id: 0xaabb (0)
Child SP       IP Call Site
GetFrameContext failed: 1
00000000 00000000 

Admittedly I could use !dumpstack but I can't figure out how to make it show the arguments. It only shows ChildEBP, Return Address and the function name. Besides it mixes managed and unmanaged calls and I'd like to focus only on the managed portions.

UPDATE

As requested by Thomas, !clrstack -i returns:

0:000> !clrstack -i

Please post the output from !dumpstack or k to double check the callstack, you know the !clrstack only display the managed code call stack, however sometimes , if the managed thread finished this work, it would be waited in the CLR code(semaphore) if you use the thread pool, and the remain call stack become totally unmanaged call stack.so !clrstack display nothing for it.
