Hi, I just installed 4GB memory to my system. In BIOS it shows up all 8x512M
chips. But after boot it shows:
$ free
total used free shared buffers cached

Does this look right? why it is 375328 KB instead of 4294967296 kB? I
compiled with 4GB mem. I did try 64GB version but after boot I got "pc_keyb
jammed" message and could not use keyboard at all.
Also I have another problem. My harddrive is: hda: WDC WD1200JB-75CRA0, ATA
DISK drive,

Drive conforms to: device does not report version: 1 2 3 4 5
If I idle the machine for a period of time (say over weekend), then on
screen it says:
dma_timer_expiry
dma status == 0x21
hda: error waiting for DMA
Then the machine completely freeze. Is that some bug already known? Thanks!

Which motherboard? Some boards will reserve some of the area between ~3.7
and 4G for various option roms and other devices present in the system.
Resulting in "lost" physical RAM.

I would most probably guess this is the case with your system.
