New AMD FX CPU not booting the pve-kernel

[ezekiel]

Hi, We have some new hardware: AMD FX 6100 CPU (6 core), motherboard is a Gigabyte 990FXA-UD7, 16 GB of RAM Kingston 1600 Mhz, non-ECC. The problem is that either pve-kernel 2.6.32 or pve-kernel 2.6.35 is not booting the system. Base instalation of Debian Lenny 5.08 with 2.6.26 kernel is booting, but it only sees 3 GB of RAM, although the bios reports 16 GB of RAM. I found some reference of the same problem on CentOS bugzilla: http://bugs.centos.org/bug_view_page.php?bug_id=5046 My biggest concern is that the pve-kernel is not even booting. Is there a chance to update the pve-kernel according to this problem ? Thank you.

not an answer to your question, but any special reason why you go for a gaming/desktop cpu instead of server cpu´s?

I reckon it's price. Desktop and server processors usually don't differ at all - they're just labeled and priced differently.

Of course server motherboards offer a lot more than desktop parts (remote management, IPMI, etc.), but for the price of a single uniprocessor DELL server I could build 2-3 similarly specced cluster nodes from desktop parts. Guess which way I'm gonna go...

Because of the six cores and price. Performance is quite good and we have good experience with the AMD X6 Phenom CPU.

I am looking forward for a fix with this issue. I opened a ticket on bugzilla too: https://bugzilla.proxmox.com/show_bug.cgi?id=53

Hi,
i guess that's must be something with your mainboard. Perhaps you must change some bios-settings/boot-params?

I have running an FX-6100 with Asus Sabertooth 990FX with ECC-Ram with pve2 - run's without problems.

Might want to check if their are bios updates for your board.
New board, new cpu, very likely there are bugs that need patched.

Bios has the latest update.
I tried a Slackware install and is working correctly, I can see the 16 GB of RAM. Also, the testing Centos kernel from http://centos.toracat.org/kernel/centos6/centosplus-testing/x86_64/ are working correctly.
So, it could be an unfortunate combination mobo/cpu for the moment, but the root problem lies in the kernel core.

did you try to our latest kernel from pvetest (http://download.proxmox.com/debian/...ve-headers-2.6.32-6-pve_2.6.32-53_amd64.deb)? if not test this one.

 

[ezekiel]

No, I haven't.
I'll give it a shot and come back with the result.
Thank you for support.

Hi,
have you tried the bootparams "noacpi noapic"?

I did a fresh install of Debian 6 and is ok, whole ram is there. After that I installed pve-kernel-2.6.32-6 from your squeeze repository, the system booted and it sees all 16 GB of ram.
So, I'm happy now and I thank you all for support.
