Hi,

This panic message occurs when virtual address 69db is read in
supervisor mode and the page is not (physically) present (error code 0)
(according to the processor handbook). Why register cr2 has such a low
address is a mystery to me at present and why it occurs so early in the
boot process is perplexing. However, that fact that is reported on two
different hardware platforms makes me less inclined to think it is some
specific hardware problem at present.  Unfortunately, this happens so
early in the boot process (before all the interrupt handlers have been
associated into the appropriate IRQ) and before printk() is OK to start
dumping messages makes this more difficult to corner.

It is still probably worth checking one's memory with memtest86+ just as
a precaution, but I am not sure how much mileage it will give us in
finding the bug.

Colin
