Ich habe einen Acer Aspire M5640 / M3640-PC mit einem Intel Core 2 Q8200-Prozessor (Quad-Core) mit Ubuntu 12.04.
Jetzt scheint es nur noch einen CPU-Kern zu erkennen. lscpu
Ausgänge:
Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 1
On-line CPU(s) list: 0
Thread(s) per core: 1
Core(s) per socket: 1
Socket(s): 1
NUMA node(s): 1
Vendor ID: GenuineIntel
CPU family: 6
Model: 23
Stepping: 10
CPU MHz: 2333.403
BogoMIPS: 4666.80
L1d cache: 32K
L1i cache: 32K
L2 cache: 2048K
NUMA node0 CPU(s): 0
Ich hätte erwartet, haben Core(s) per socket
und CPU(s)
haben 4
hier als Wert aufgeführt.
Ein wichtiger Hinweis ist, dass ich es nicht regelmäßig booten kann, aber ich brauche den nolapic
Kernel-Boot-Parameter, um ein hartes Einfrieren während des Bootens zu vermeiden.
Apropos Booten, die Firmware-Version ist Version: R01-C2
Alle Gedanken zur Fähigkeit, alle vier Kerne zu verwenden, werden sehr geschätzt.

). Ich grabe die Informationen aus (Motherboard & BIOS-Version). Sie kennen vielleicht einen magischen Befehl, um ihn auszugeben;)
dmidecode
schien zu funktionieren (ich habe den Originalbeitrag bearbeitet).
lshw -class cpu
Befehlsausgabe hinzugefügt und es scheint, dass die CPU "Intel (R) Core (TM) 2 Quad-CPU Q8200 bei 2,33 GHz" ist. Ich weiß nicht, ob das hilft. Ich werde 12.10 Live-CD versuchen und auf dem Laufenden bleiben.
