Hi, At some point, I discovered that I only had one processor active on my laptop (A VAIO VGN-SZ2M) wich has a centrino duo in (2 cores). I then discovered in dmesg the lines that say: ACPI: BIOS bug: multiple APIC/MADT found, using 0 ACPI: If "acpi_apic_instance=2" works better, notify linux- acpi@xxxxxxxxxxxxxxx So I did that (acpi_apic_instance=2) and that did give me 2 processors. Which is definitely better, hence my email to the suggested address. There is one thing that does not quite work however and I don't know if this is related: ACPI only sees one processor and therefore cpufreq only controls the frequency of one processor. I think this used to work but I don't know when that stopped. Hee's the output of uname: # uname -a Linux pcp2ffl 2.6.30-gentoo-r8 #4 SMP PREEMPT Thu Nov 12 18:41:51 GMT 2009 i686 Genuine Intel(R) CPU T2300 @ 1.66GHz GenuineIntel GNU/Linux I have tried with a vanilla kernel too but that made no difference. Hope this helps.
