CPU not detected on a Compaq Proliant 3000 dual P II 400 Mhz

[Joachim Davain]

Binary package hint: linux-image-2.6.15-23-server

I made an installation of 6.06 server on a Compaq Proliant 3000 dual PII 400 Mhz, but only CPU 0 is detected. The 2 CPUs are OK for the bios. I exchanged the 2 CPUs and I get the same result only CPU 0 is detected.

Please attach dmesg (do no paste in comment).

[Joachim Davain (joachim-davain)]

Here is dmesg

[Gareth Fitzworthington (mapping-gp-deactivatedaccount)]

This bug has had no activity for a considerable period. This is a check to see if there is still interest in investigating this bug report.

[Joachim Davain (joachim-davain)]

Yes, there is still interest in investigating this bug report.

[Gareth Fitzworthington (mapping-gp-deactivatedaccount)]

Has this been tested this against any later Ubuntu releases?
Has the hardware been verified OK? (ie. not just CPU's)
Is this issue tested against any other Linux distributions or other OS's?

[Joachim Davain (joachim-davain)]

The hardware is OK according to the BIOS utilities.
I cannot test against other OS's as the server is in production.
I will try with the 8.04 LTS when it will be released.

[Gareth Fitzworthington (mapping-gp-deactivatedaccount)]

Joachim,
Are you able to try the following?

sudo dmidecode > dmidecode.txt
sudo biosdecode > biosdecode.txt
sudo ownership > ownership.txt # Note: this is a Compaq specific command.

If so, please attach resulting text files.
Thanks.

[Joachim Davain (joachim-davain)]

Here are the requested files

[Joachim Davain (joachim-davain)]

Ownership output is empty.

[Gareth Fitzworthington (mapping-gp-deactivatedaccount)]

Joachim,
OK. Pre-SMBIOS system. Your system was manufactured pre-1999 (probably). However, it does appear to have ACPI functionality. This appears to be disabled by default on your system probably due to it's age. You could try booting with "acpi=force" kernel option? Long-shot!

++++++++++++++++++
Note to Kernel Team:
1/ This is a Pre-SMBIOS system.
2/ Summary of problem: Second CPU not recognised.
3/ It appears to have ACPI functionality, although unsure if it's supported.
4/ Compaq Proliant 3000 was originally sold with Linux support (Suse 6&7 & RH 6&7 )
5/ Firmware & documentation can be searched for here http://h20000.www2.hp.com/bizsupport/TechSupport/ [search for "proliant"]
6/ Firmware updates (Linux supported) are available and where released as recently as 2005.

Leaving this with the Kernel Team to decide upon "Won't Fix" or otherwise.
++++++++++++++++++++++++++++++++

[Joachim Davain (joachim-davain)]

Gareth,

No change with acpi=force and same dmesg output.

[Joachim Davain (joachim-davain)]

Gareth,

I upgraded to 8.04. The problem remains the same (with or without acpi=force).

[Gareth Fitzworthington (mapping-gp-deactivatedaccount)]

Joachim,
Can you examine the following link?:
http://forums11.itrc.hp.com/service/forums/questionanswer.do?admit=109447626+1209379186243+28353475&threadId=200797
In particular the section regarding the following:
/QUOTE{
    0. Boot To System Configuration Utility (F10)
    1. At main menu press Ctrl-A (or Ctrl-Q) to activate Advanced mode
    2. Select System Configuration
    3. Select Hardware Configuration
    4. Select View and edit details
    5. Change APIC Mode to Full Table (or Full Table Mapped)
}/ENDQUOTE

Reply:
 "The APIC setting was the problem. The proper setting (in this circumstance) was FULL TABLE not FULL TABLE MAPPED. I've now got a proliant 3000 server running dual 550s."

Your system is a little different but similar APIC change maybe worth a try.

[Joachim Davain (joachim-davain)]

Gareth,

I looked at the link you gave me, but in my case the POST reports that both processors are running fine.

Anyway, I tried but the System Configuration Utility is not available on my system.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

[Launchpad Janitor (janitor)]

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

I have had this problem in both 2.6.31-17 and 2.6.32-9 (both generic and using the compiled-in acpi-cpufreq)

The CPU is a Duo 2 T2500 @2GHz, as shown, but the GHz is shown as 1GHz. This throttles down my CPU to a maximum of 1GHz, making frequency scaling impossible. I have tried disabling scaling in BIOS (Dell Latitude D620, v.A10) to at least get the cpu to run at a constant 2GHz so I can work while waiting for a fix. No joy so far. Have even thought of compiling the old speedstep-centrino driver as a module, but not done with that time-intensive experiment yet.
