Kernel Panic (ACPI problem) with new mobo and Slackware 12.1.
 

I had an Asus A2MN-SLI motherboard which died, so I bought an Asus M2N-X to replace it, keeping all my other parts. Anyway, my Slackware installation was no longer working - I think I'd get a black screen before the actual booting started, so I formatted the partition and decided to install again.

If I just type enter to have hugesmp.s used as the kernel, I get the following error:

"Kernel panic - not syncing: IO-APIC + timer doesn't work! Boot with apic=debug and send a report. Then try booting with the 'noapic' opetion."

Did as suggested, here's what I could see with debug:

"ENABLING IO-APIC IRQs
..TIMER: vector=0x31 apic1=0 pin1=0 apic2=-1 pin2=-1
..MP_BIOS bug:8254 timer not connected to IO_APIC
...trying to set up timer(IRQ0) through the 8259A ... failed
...trying to set up timer as Virtual Wire IRQ ... failed
...trying to set up timer as ExtINT IRQ ... failed :(."

Then the same error message.

I've tried installing with the huge.s kernel, and while it does work, my pppoe-start doesn't connect after I set it up. I think it's because some necessary module may not be loaded, but I'm too much of a newbie to understand what's going on.

I'll reboot to try installing it with the noapic option as suggested, though I was wondering if anyone has a solution to my problem.

Also, I don't think it matters, but my processor is an AMD Athlon X2 4200+.

Edit: noapic got it installed, but pppoe-start still doesn't work, giving me the following error:

"/usr/sbin/pppoe-start: line 191: 3375 Terminated $CONNECT "S@" >/dev/null 2
>&1"

Hello and welcomde to LQ forum,

Did you try to run a live-CD (whatever distribution) just to make sure your hardware is correctly connected/set up?

I'm not sure I understand at which point you tried to run pppoe-start. Did you complete successfully the installation and you exited and rebooted or did you try to run ppoe-start just after logging with the installation CD?

What is your network device? Do you really want to connect using PPPoE (Point-to-Point Protocol over Ethernet)? If you do not know, please provide the result of the following commands:

Hello,

I have goten pppoe to work with my installation. It was a matter of correctly setting one of the ip addresses and network mask.

As for the ACPI, I'd like to get it to work, since with it my computer would be faster.

Edit: What would have to be wrongly connected for this ACPI error to occur? I imagine this is a problem between the motherboard, CPU and Linux and I'm pretty sure both the motherboard and CPU are correctly set up. Well, I think they are.

You could be asking about it due to the pppoe problem though, in which case disregard this.

I think I fixed a similar problem with a BIOS update... M2N-SLI Deluxe. It was some time ago but from memory the issue was very similar.

What ? How would that be ? also APIC is not ACPI

Anyway, I agree with mRgOBLIN, that it is likely a BIOS issue. Update your BIOS and see if it fixes things. A temporary solution is booting with either 'noioapic' or 'noapic'.
