Subject: 4Gb memory?
Date: Mon, 27 Oct 2003 14:15:17 -0500 [thread overview]
Message-ID: <BAY7-F103askCcBONAA0000a470@hotmail.com> (raw)
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
Mem: 3753328 566800 3186528 0 96040 189960
-/+ buffers/cache: 280800 3472528
Swap: 2096440 0 2096440
$dmesg

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,
hdparm -i /dev/hda
/dev/hda:
Model=WDC WD1200JB-75CRA0, FwRev=16.06V16, SerialNo=WD-WMA8C2065737

PIO modes: pio0 pio1 pio2 pio3 pio4

UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5
AdvancedPM=no WriteCache=enabled
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!
