Re: Problem booting RH8.0 with SMP kernel after fresh install

where in the boot process does it reboot? If needed setup a serial console.

The kernel would just get into about 1 second of the boot and then barf, screen blank and reboot.

I followed what some people had to say about it earlier, and added things like:

noapic

to the kernel parameters and then booted but to no effect.

When I added maxcpus=1 as a kernel parameter to the smp kernel, it did actually boot and gave me a bunch of APIC info though, like it just didn't like the 2nd cpu.

Perhaps if the kernel has ACPI support it may be barfing on that. I had
a Dual P2-233 with Asus P2L97-DS, had suse 7.3 on it, when I tried to upgrade
to 8.0 it locked up hard on the SMP kernel(UP kernel worked fine as in your
case), I traced it to the ACPI code, recompiled the kernel w/o acpi and
it was fine(trying the various apci options to disable the driver didn't
work for me). Dual 300 is similar enough that the problem may be the
same. Perhaps your board doesn't support ACPI(on mine, I found no traces
of ACPI support in the BIOS, though I can't say for certain if it supported
it or not).

I'm not 100% sure whether the mother board supports it, but I have the manuals somewhere that I can check. I know with my Acer Altos 1100 server, it does have ACPI features.

As above, I tried using the noapic kernel paramter but to no avail.

I've configured a kernel to not use that code etc, but I have a problem compiling the thing, which we're also discussing in another thread.

I've never used grub, but there should be info via google or whatever on
how to setup serial console with it.

For now I've removed the 2nd cpu and terminated the slot, for it's not critical that I have it dual. When I have the kernel compilation issues worked out, I may go back and look at that problem again.

Thanks for your help though.

Michael.
