problem booting SMP kernel !
Date: Mon Nov 08 2004 - 03:47:49 EST
I have been trying to boot an SMP kernel (2.4.20 redhat) on my laptop
(Dell Inspiron 5160) without any success.
It has hyper-threaded processor (Pentium IV 3.0 GHz - HT). 2.6.5 kernel is
booting fine and is able to detect the
Hyperthreading and initilize it and I can see two processors in my
/proc/cpuinfo with 2.6.5 booted up.
I searched around the internet to find out if i can get some other kernel,
or if someone has succeded in getting
SMP up on these laptops. I also tried 2.4.24 and 2.4.27 from kernel.org. But
all of them seem to stop at the same place.
Here is the log for 2.4.27 kernel bootup
ESR value before enabling vector: 00000000
ESR value after enabling vector: 00000000
Booting processor 1/1 eip 2000
Error: only one processor found.
Warning: No sibling found for CPU 0.
Using local APIC timer interrupts.

---------------------------- HANGS here, for
I can send the 2.6 kernel bootup log if required !
Somewhere on the net i read that this problem is due to buggy BIOS on these
laptops, it has some problem
with APIC's. But it boots up all well with 2.6 kernel, so i think i can make
it work with 2.4. too. I have some idea
about the linux kernel and can backport the stuff from 2.6 with some help.
To be precise, if someone can
point out the cause of the problem.
I have tried the options like "acpismp=force", "acpi=off", but the problem
seems to be beyond it.
If someone has a quick workaround to make it work please let me know.
I am sending this mail for second time .... if anyone has any pointers
please send it over.
