This is expected behaviour when CONFIG_NET_SCH_CLK_CPU is defined: Say Y here if you want to use the CPU's cycle counter as clock source. This is a cheap and high resolution clock source, but on some architectures it is not synchronized on all processors and doesn't handle cpu clock frequency changes. > Any known way of dealing with this without having to disable > cpufreq? Yes, specify a different clock source in your kernel configuration. --atj _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
