Re: Raising temperature threshold
Some sysctl's can not be changed on a running system try reading the defaults/loader.conf in /boot/ see if you can change the acpi thermal setting in there if not just add those sysctl with a = 50C etc.. to loader.conf and reboot On Wed, Jun 22, 2005 at 01:52:22PM -0300, Matthew Flanagan wrote: On 22 Jun 2005 11:46:31 -0400, Lowell Gilbert [EMAIL PROTECTED] wrote: Matthew Flanagan [EMAIL PROTECTED] writes: I`ve installed a FreeBSD 5.4-STABLE and I was building some ports when suddenly my system shut down.

Re: Raising temperature threshold
Hi, I don't think it is advisable to put your machine under such strain. I think 60C is already very hot for regular parts, and that it is proper that the machine would shutdown . Unless you have a special military kind of hardware, I am sure that more than 60C will reduce the MTBF of your hardware, and maybe void your warranty if you have one. It would be interesting to know if that setting can be changed to a _lower_ value, in fact. -- # Bruno Gallant - [EMAIL PROTECTED] - [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
