I've got an AMD Sempron machine running FreeBSD 6.0 that's been

The panic message is TPTE at 0xbfc20624 IS ZERO @ VA 08100000
bad pte
This started last night while I was portupgrading ruby and I got
random apps segfaulting, mostly gcc, so I suspected bad memory. I
installed new memory today, tried to buildworld. And *BAM* panic:
bad pte
I'm still guessing that this is a hardware problem, and not
software but I'm not sure. If anyone can give me a clue I'd
appreciate it.
Machine details:
AMD Sempron
ECS K8M800-M2 mainboard
1 GB Kingston PC-3200.
Thanks,
Matt
First, a quick Google of "bad pte" turns up some ideas. Try
disabling or changing APIC and/or ACPI settings. Make sure your
swap partition is error free and has enough room. Google a bit
more just on the lists.freebsd.org site for several possibilities.
Yeah, I was wondering if it might be something in the BIOS
settings. I'll google around and see what I find. I don't know if
the first panic was a bad pte error since the machine was running
headless.
For hardware, you can try memtest86+ to check to make sure the new
memory is good. There are other stress tests you can run as well -
I usually use the ultimate boot CD for that stuff. Other possible
problems are faulty or too small power supply; too much heat on
CPU, RAM, or expansion boards; faulty expansion cards and/or
components; or faulty hard drive.
I kinda wondered if heat might be an issue, since it was kind of
tucked away in a spot with bad airflow. I'll try the memtest thing.
Is there a way to get the CPU temp in FreeBSD?
Meh. let's see if this thing'll actually compile...\
Gahhh!
# cd /usr/ports/sysutils/memtest86
# sudo make install
*snip*
* Usage:
*
* 1) Insert blank floppy
* 2) dd if=/usr/local/share/memtest86/floppy.bin of=/dev/fd0
* 3) Boot the floppy
which would be all well and good if this machine actually had a
damned floppy drive.
C'mon kids. Let's catch up to the late 90's....
*BAM*
savecore: writing core to vmcore.5
*HATE*
