Hi,
I tried this on Fedora 14 and OpenSuse 11.4 and both exhibit the same
behavior. 8GB is installed but only 2698476 shows available for use
using "top" or "free". dmidecode shows 2 4GB DIMMs and the BIOS reports
8GB of memory. Memtest reports and tests 8GB of memory. I Googled the
issue and it seems there are others that also report the same. What to
do? Thank you.
Best,
Chris

/proc/iomem?
dmesg?

Also, do you have the latest BIOS? If not, can you update it? Also, can
you try the latest upstream kernel to verify the problem still exists?
Thanks.

It was already asked for, but dmesg is certainly helpful. Please send
the dmesg of a kernel boot.

Something else you could try is update your Fedora 14 kernel since the
latest version supposedly contains a fix which is relevant to your
issue:

Thank you to those who gave suggestions about the issue I saw. Updating
the kernel to 2.6.39, for me, fixed the problem.
Best,
Chris
