Howdy,
I just added RAM to my computer, and upon boot I get a panic. I'm
enclosing the debug session script output, but first a bit of
background...
The computer has two slots for DIMMs, and was using both before, with
generic 256MB sticks. I removed both of those and put in two 512MB
sticks of Kingston PC2700 RAM - and that's when I got the panic.
Test 1 - switch the positions of the sticks (swap slots). Same result.
Test 2 - Remove one stick. Successful boot.
Test 3 - Put that same stick in the other slot. Successful boot.
Tests 4, 5 - Repeat tests 2 and 3 with the other stick. Successful
boots, both.
Test 6 - One 512MB stick and one old 26MB stick. Successful boot.
Test 7 - Swap slots. Successful boot.
Tests 8, 9, 10, 11 - various combinations of sticks and slots.
Successful boots, all.
Also, I added a swap file so that I'd have a bit over 3GB swap space.
I'm including swapinfo output at the bottom...
So my comclusion is that FreeBSD is having trouble booting with 2 512MB
RAM sticks. The BIOS recognizes the RAM ok (see the debug out put,
below).
Help? Thank you...
