With -CURRENT up to 2006-02-12 06:57:41 UTC (last commit by scottl) I still can see some calcru messages: calcru: runtime went backwards from 3508844 usec to 3508842 usec for pid 28 (pagezero) u 0:0/0 s 440:3508844/3508842 i 0:0/0 calcru: runtime went backwards from 58271630 usec to 58271602 usec for pid 10 (idle) u 0:0/0 s 8655:58271630/58271602 i 0:0/0 [...] calcru: runtime went backwards from 111507 usec to 111506 usec for pid 484 (login) u 8:68619/68619 s 5:42887/42886 i 0:1/1 calcru: runtime went backwards from 3508842 usec to 3508841 usec for pid 28 (pagezero) u 0:0/0 s 440:3508842/3508841 i 0:0/0 There are no repeated messages about madplay, as it was before. CPU is overloaded in this test (usually each madplay process uses about 12% on my system, and in this test each process has only about 7% of CPU to run. In normal conditions only one or two are running, other are in 'pcmwr' state (according to top), in overloaded system all madplay processes are 'running'. Yuriy.
