Subject: PROBLEM: Incorrect RAM Detected at kernel init
Date: Sun, 21 Aug 2005 23:27:51 -0400 [thread overview]
Message-ID: <001001c5a6c9$7a0e1df0$6301a8c0@finian.net> (raw)
Not sure if I have provided enough info, or to much info, but here it goes:
[1.] One line summary of the problem:
Not Detecting all the memory installed in the system.
[2.] Full description of the problem/report:
I have Linux Kernel 2.4.31 running on a Compaq 5000R server with 2 PPro 200
processors, 768M RAM, RealTeck 8139 Network Card, and Compaq Smart 2 Raid
controller with 5 9.1G drives in Raid 5 configuration.
The kernel appears to compile perfectly, installs fine, but after reboot it
is only reporting 16M of RAM. I have tried with and without the mem=768M
boot up option in the lilo.conf script. All other modules and boot up
includes appear to run perfectly fine. I had a 2.4.18 kernel running on this
box just fine, detected all 768M of RAM and ran perfectly. The 2.4.31 Kernel
runs almost perfectly, the only hold back is the false detection of memory.
[3.] Keywords (i.e., modules, networking, kernel):
kernel
[4.] Kernel version (from /proc/version):
Linux version 2.4.31 (root@tunes) (gcc version 3.3.4) #3 SMP Sun Aug 21
10:34:35 EDT 2005
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
[6.] A small shell script or example program which triggers the
problem (if possible)
N/A
[7.] Environment
[7.1.] Software (add the output of the ver_linux script here)
If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.
