As I'm running current, I didn't really take care of them because -current is not intended to be stable and people also had problems (that is the game). After 2.1.5, -current seems to be ok for people and I still have problems with my box. Particularly after an idle time, when the activity is increasing again. As I use 3 disks for swapping, I thought this was because of a too important need of power, so I disabled one of the swap areas. I was close to the solution when for the first time I decided to stay at the console (I usually start X) and wait, wait, ... I finally got the answer: trap 19 NMI (aka power fail NMI), bingo! I since run a kernel with `options POWERFAIL_NMI' and for the first time received a beep and a Aug 19 20:31:35 xp11 /kernel: NMI: power fail as expected, but my box is *still* alive. I hope this can help! ------ ------ Philippe Charnier charnier@lirmm.fr (smtp) charnier@xp11.frmug.org (uucp) ``a PC not running FreeBSD is like a venusian with no tentacles'' ------------------------------------------------------------------------
