Hello! I am having some problems with booting from the Gentoo Minimal Install CD. If I boot without any options, the kernel seems to proceed fine until it's time to load the scheduler (Deadline), where it just hangs up.
On the other hand, booting with the "acpi=on" option explicitly gives me a kernel panic saying it can't sync the timer with IO-APIC.
Specifying "noapic" at boot time fixes the above problems but after a variable amount of time, everything hangs up with "IRQ 7: nobody cared".
The only way I can boot normally is by using both irqpoll and noapic. But I have a dual-core CPU (AMD Athlon 64 X2 5200+), and I heard noapic disables SMP.
What can I do to fix this? |

Lysergsaure,
Its not a long term problem and will be fixed when you configure your own kernel.
You can install on one core, then make your own kernel.
