Fatal trap 19 on Sony Vaio

[TechNews]

I'm getting the following trap when i try to install from  the i386 
7.0RC1 disk1 and livefs install cds. I've also tried booting with acpi 
disabled.  The error says it's a RAM issue but since i've been able to 
boot other operating systems on it without a problem. The laptop is a 
Sony VGN-FZ240E. The problems seems to be fixable by building a kernel 
without firewire but is there a way to get the stock kernel to work?

This is what's on the screen after the panic:

fwohci0: [MPSAFE]
fwohci0: [FILTER]
fwohci0: OHCI version 1.10 (ROM=1)
fwohci0: No. of Isochronous channels is 4.
fwohci0: EUI64 08:00:46:03:02:90:3b:12 u
NMI ISA b0, EISA ff
RAM parity error, likely hardware failure.

I tried some iso's i had lying around and I was able to get into 
sysinstall on 4.3/4.8,5.0, 6.1 and i'm currently
 running Vista without a problem. A PC BSD 1.4.1 (6.3 PRERELEASE) also 
panicked.

When booting nothing is attached to the firewire port.
