hi, 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 Not responding. Error: only one processor found. Warning: No sibling found for CPU 0. Using local APIC timer interrupts. calibrating APIC timer ... ..... CPU clock speed is 3056.5842 MHz. ..... host bus clock speed is 0.0000 MHz. cpu: 0, clocks: 0, slice: 0 ---------------------------- HANGS here, for ever --------------------------------------
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.
thanks, -rpm
