Hi,

Have a look at Message-ID: <000901c1944f$9854dc30$c806a8c0@lfarr>.
Titled "Fatal trap 12 when running mergemaster."

I was having a lot of strange crashes on a previously rock-stable
machine.
After swapping every component, I gave up and put in a SCSI disk. 
It ran as solid as a rock again through about 6 or 7 makeworlds, X11 and
KDE
builds. Moved the install back to another disk (I ran the IBM low level
disk
tools on the disk first, and it passed). Within an hour I had a panic.
It was a corrupt directory error, but it rebooted before I had chance to
write
down the error. I newfs'd it last night, and left it run with no
problems,
and it's buildingworld again now.

It's an Asus A7V133, and it's Crucial RAM, and a decent 300W supply.

Here's a dmesg
