I understand your point, but maybe there is some missunderstanding. I disabled in my BIOS and in my config file, as you can see in my previous e-mail. This as far as I can tell leaves no code for power management in the kernel. (via strings /kernel|grep -i apm, or strings /kernel | grep -i power ). It leaves however a code that detects the pci chipset. I don't if that is what you're talking about (detecting it at the pci level), but if it is that, I really don't know how to disable it. - One more thing, my HZ is set by default. I have heavy usage of DUMMYNET subsystem, and in the LINT it is said that I should make it more granullar(HZ=1000), but my expectaions are, this may worsen the situation. Am I right on my expectations? - Zvezdelin Vladov To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
