FreeBSD 4.8-RELEASE-p13 The machine overheats. sysctl variables unable to be seen. Box-1 = NFS-server (the problem machine) Box-2 and above are NFS-clients The short version of the problem: After some overheating issues using: Two (2) AMD 1800+ MP processors In a Tyan Tiger MP (S-2460), it was discovered that setting the following knobs curbed the overheating: machdep.apm_standby_delay=0 machdep.apm_suspend_delay=0 Things went pretty smooth --for a while. Currently, we have the same two (2) AMD 1800+ MP's in a different board ="Tyan Tiger-MPX (S-2466)" -- now the box continues to overheat just as it did in the past (prior to setting the above sysctl knobs). When switching from the S-2460 to the S-2466, all we did was plug in the hdd's and go for it --things seem to work. Because the S-2466 is the successor to the S-2460, we didn't see any need for a fresh install --granted the chipset is a tad different. <g> Could this different chipset be causing my problem(s)? Looking further into the problem, on Box-1: # sysctl machdep.apm_standby_delay sysctl: unknown oid 'machdep.apm_standby_delay # sysctl machdep.apm_suspend_delay sysctl: unknown oid 'machdep.apm_suspend_delay' As you can see, these knobs are no where to be found. The extreme strangeness is, The roll of this machine is one of a build-box; three (3) other machines on the LAN mount the necessary file systems via NFS to installworld and install their respective kernels from this machine, and yet, on those client machines I get the following: # sysctl -a | grep -i apm SWAPMETA: 160, 3479, 489, 227, 1592 debug.apm_debug: 0 machdep.apm_suspend_delay: 1 machdep.apm_standby_delay: 1 --------------------------------- Using that same command on the --build machine-- aka: Box-1: # sysctl -a | grep -i apm SWAPMETA: 160, 31727, 0, 0, 0 <-- is all we get. My questions are, at the very least: Why aren't those knobs -or- variables displayed using sysctl -a? Even though the aforementioned variables aren't seen using the above command, will setting those *unseen variables in /etc/sysctl.conf in fact get set? Thanks for your time reading this. ------------------------------------- All incoming attachments get deleted. Have a nice day. -------------------------------------
