'Twas brillig, and Lennart Poettering at 23/02/09 02:05 did gyre and gimble: > OpenSUSE apparently does not enable it. The same is true for > Ubuntu. Same for Debian. Note sure about Mandriva. Here is a (not quite current) grep from my running kernel (it's .27 as .28/.29 both break my intel graphics :( at the moment): $ zgrep -E "HZ|PREEMP" /proc/config.gz CONFIG_PREEMPT_NOTIFIERS=y CONFIG_NO_HZ=y # CONFIG_PREEMPT_NONE is not set CONFIG_PREEMPT_VOLUNTARY=y # CONFIG_PREEMPT is not set # CONFIG_HZ_100 is not set # CONFIG_HZ_250 is not set # CONFIG_HZ_300 is not set CONFIG_HZ_1000=y CONFIG_HZ=1000 CONFIG_MACHZ_WDT=m I'll ask our kernel team why PREEMPT is not on as I've no idea of the consequences. My guess is that it relates to graphics drivers...
