acpi_apic_instance=2 and a question

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

kernel 2.6.33.7

laptop from ECS aka ELITEGROUP aka Uniwill
model L75II0
Intel Core2 Duo T5750 2GHz
Phoenix BIOS

It's different, maybe better, with acpi_apic_instance=2

If you'd like more details / output from anything (dmesg? acpidump? dmidecode? whatever) please ask.

I'd like to get Linux running better on it - only starts 1 CPU whereas sadly Vista starts both cores.  Any suggestions welcome!

I've tried newer test kernels for ArchLinux (sorry, not yet kernel devel / Linus ones) and both 32-bit and 64-bit only start 1 core.

I'm currently looking at files such as smpboot.c and drivers/acpi/tables.c but don't really know what I should be doing to try to understand the sequence of events so I can try to work around what is no doubt a buggy BIOS.  No BIOS updates available from maker's websites.

Thanks,

John
