The problem is in kernel settings: sysconfig(_SC_CLK_TCK) reports 100, but the actual value is equal 1024. As the result all programs which try to make decision about time correction could work incorrectly (ogle, xine and other soft realtime programs). For example the short program at the end of this letter returns on my system: clocks: 100 times1:1280320765 1 sec pause times2:1280321790 (times1 - times2) must be near clocks value, but: 1280321790-1280320765=1025 #include <stdio.h> #include <sys/times.h> #include <unistd.h> struct tms dummy_tms; int main (int argc, char *argv[]) { printf("clocks: %li\n", sysconf(_SC_CLK_TCK)); printf("times1: %li\n", times(&dummy_tms)); sleep(1); printf("1 sec pause\n"); printf("times2: %li\n", times(&dummy_tms)); }
known problem in current gentoo-sources, I just tested on current lolo-sources and it werks tasty fine, and so will work tasty fine on the next gentoo-sources.
