Re: disk spinning continuously + cpu possibly overheating = sudden death
Hi Chuck, I ran memtest86+ by loading it from the loader prompt. It completed Pass 1 with no errors in about 45 minutes. While I'll re-run memtest86+ for at least 2 passes tonight, I more suspect bad blocks in my ffs slice. So I am planning to install sysutils/smartmontools and run smartctl on /dev/ad8s2 (the ffs slice). Is there any port for monitoring system thermals, particularly CPU ?

Hi Chuck, What do I make of it when the system runs flawlessly both on Win XP and FreeBSD-8.0-amd64 ? BTW, 8.2 does NOT - for reasons unfathomable to me - install /usr/sbin/apmd. I don't know how significant that is, but I have had to insert into rc.conf : apm_enable="NO" apmd_enable="NO" Thanks for any help.

disk spinning continuously + cpu possibly overheating = sudden death
Hello all, I am running FreeBSD-8.2-amd64 on a Western Digital 320 GD disk and a quad-core AMD Phenom processor. After booting, the disk keeps continuously (meaning continuous I/O) and after a couple of hours (on the console with the X server not running), suddenly the whole system dies, powering off in a flash. I suspect the continuous I/O is causing is a CPU overheat which results in this behaviour. The strange thing is when I ran a script to ktrace and kdump, there is no sign of any unwarranted I/O. Can anyone suggest what possibly be wrong with my system ? I have disabled as much as possible in rc.conf and syslog.conf to prevent I/O. My script and the output are pasted below. BTW, the system runs flawlessly both on Win XP and FreeBSD-8.0-amd64. The reason I do not want to install FreeBSD-8.0-amd64 is that its Logo saver, one of my al-time favourites, does not work. In 8.2, it does work. One thing I should mention is that, apart from swap, I have only one partition / (35 GB). No other mountpoints. BTW, does FreeBSD have anything like Linux badblocks to check for any bad sectors in hard disks ? Thanks for any help.
