Hi,

With 2.5.60, dcachebench no more completes. All threads
go to sleep as below. Last time I tested was with an intermediated BK diff
(diff-bk-030204-2.5.59) and it was working fine.

I tried "./dcachebench -p 4 -b junk" on a 4-way SMP with pre-epmtion ON.

dcachebench is available at
http://www-124.ibm.com/developerworks/opensource/linuxperf/dcachebench/dcachebench.html
