I am installing CentOS 6.0 on an Asus E35M1-M Pro to make an energy efficient server.
The results so far with this board are only moderately encouraging, when putting high load on the harddrive i get time out errors and i found a lot of postings on forums about trouble with the onboard network card but anyways, back to the real problem
This mobo is equipped with the AMD A50M Fusion chipset and AMD Fusion E-350 CPU.
When CentOS is booting, it is only recognizing 2.6 Gb of the available 8 Gb RAM.
This has to do with a patch that got included in kernel 2.6.38 but apparently is not included in the stock RHEL6 kernel.
I tried installing CentOS plus kernel, no change.
dmesg says this :
New variable MTRRs
reg 0, base: 0GB, range: 2GB, type WB
reg 1, base: 2GB, range: 512MB, type WB
reg 2, base: 2560MB, range: 128MB, type WB
reg 3, base: 2687MB, range: 1MB, type UC
e820 update range: 00000000a7f00000 - 000000023f000000 (usable) ==> (reserved)
WARNING: BIOS bug: CPU MTRRs don't cover all of memory, losing 5103MB of RAM.
Some more information about AMD's kernel patch here :http://amailbox.org/mailarchive/linux-k ... /4/4627743
And a thread on the Asus support site here :http://vip.asus.com/forum/view.aspx?id= ... -us&page=2
Where can i make a request for the update to be included in the CentOS plus kernel or is there any repository i can switch on to get a newer kernel for my box?
Thanks a lot for any help!
