Inst= alled RedHat and FreeBSD and both rebooted periodically. Don't know if my solution wi= ll help or not, but what was causing my reboots was the system BIOS. The options for Pow= er Management in the system BIOS should have some settings for the monitor as well as t= he hard drive. I was finding that the spinning down of the hard drive caused the machine= to reboot. No traces in any error logs or anything... Hope that helps somebody...somewhere... :) Arthur Jim Mercer wrote: > On Tue, Mar 21, 2000 at 12:06:05PM +0100, Pawe=B3 Dubin wrote: > > > the first system runs 3.4-stable and gets spontaneous reboots infre= quently, > > > and there are no messages (dmesg, console or syslog) indicating why= it rebooted. > > > the new system runs 4.0-stable, doesn't have vinum, and is spontane= ously > > > rebooting (several times in 48 hrs). again no messages indicting t= he problem. > > > > We have similar problem (the same configuration but RH 5.1) (I dont k= now what > > is vinum).
