Hi,
After some rereading shm swap code I rewrote my swap test program to
use anonymous mmap instead of shm to drive my machine into swapping
and viola:
shrink_mmap: unknown LRU page!
kernel BUG at swap_state.c:49!

The stack is not complete, my serial console truncated the lines.
This is on 2.3.40+smp-41-A2 from mingo with HIGHMEM enabled and 8GB 8way.
I am restarting the tests now with HIGHMEM disabled.
Greetings
Christoph
