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.
Regards
Manish Jain
