Hmm. It appears that some of the processes are stuck on this part of page_launder:
/* * Re-take the spinlock. Note that we cannot * unlock the page yet since we're still * accessing the page_struct here... */ spin_lock(&pagemap_lru_lock);
It will be interesting to see what's going on in each of the cpus. Use "cpu x" x=0,1,2,3 on your 4 cpu system to switch to cpu x, and just type "bt" on each cpu. Also, it will be good to see what kswapd (pid 2) is upto ...
