Has the 11.2 RC2 kernel stolen a CPU?

Uh?

Yours is no a Transmeta CPU, it's an Intel Dual Core :-?

The system is an HP{ Pavilion Slimline s3160.nl.
They say it has a Pentium E2140 (C) 1,6 GHz CPU.

And that is what the 10.3 kernel says likewise.
How can such a thing happen???
(I haven't even heard of such a thing as Transmeta)

Look this thread:

***
A core missing!

And:

***
After upgrade to version 9.04, Ubuntu uses only one processor.

It seems you are facing some similar problem :-?

Very odd behavior indeed, but just to be sure, that there is no bad boot parameter, show us the output.

cat /proc/cmdline

*Cough*, as a "Disciple of Linus the Great", you should have (hint, read the WP article about Linus).

It does not seem to be a global problem. For example my Intel core i7 920 shows all cores with "dmesg | grep CPU" when booting to the openSUSE-11.2 RC2 64-bit KDE-4.3.1 liveCD : pastebin - dmesg output - post number 1649487

[hcvv]

On 11.2 cat /proc/cmdline:

root=/dev/disk/by-id/ata-Hitachi_HDT725032VLA380_VFJ201R23XUEXW-part5 nolapic resume=/dev/disk/by-id/ata-Hitachi_HDT725032VLA380_VFJ201R23XUEXW-part1 splash=silent quiet vga=0x31a

An yes, after Camaleón mentioned Transmeta I did some Wikipedia reading.

I am not quite sure I understand all the stuff in Camaleón's links, but I tried to boot with acpi=off and with noapic (not with both at the same time. Didn't help. Maybe I just tried the wrong thing.

I remember that when booting the 11.2 RC2 DVD it ended up in a loop after loading the kernel. I then tried playing with the F-keys and the parameters until it did. I am not quite sure which one (also some acpi), but will try later to reconstruct this (first the wife calls for dinner ).

Strange imho is also that also it says Transmeta in the first place, it says Intel on the My Computer page.

And to make the story complete, here is /proic/cmdline from 10.3:

root=/dev/disk/by-id/scsi-SATA_Hitachi_HDT7250_VFJ201R23XUEXW-part2 vga=0x31a resume=/dev/sda1 splash=silent

And that brings me the main extra one there: nolapic. Shall I try without it?

Japp, remove the "nolapic" for a start.

[hcvv]

Removing the "nolapic" resulted in a loop while booting. Black screen for a while and then a system start.

O.k, then try first booting with the "safe-setting" option of the Grub menu
(which I guess auto-disables acpi, apic and so) and then check again if the
2 cores are present.

Sorry I did not tell this, but direct after the boot loop I tried "Safe Settings". It booted, but only one CPU.
