Hi all,
I have a brand new T2400 core duo laptop and some problems...
SMP realtime patched kernel hangs at kernel boot.
I first try FC5/PlanetCCRMA with 2.6.16-1 out of box kernel. Both SMP
rrt and rdt doesn't boot, non SMP versions works flawlessly.
Then I try to compile 2.6.16 with rt26 patch and 2.6.17-rt7 on Ubuntu
6.06 with the same results. SMP hangs, UP works well.
Non realtime patched SMP kernel works nice.
Does anyone experience the same?
Maybe (I hope!) I made a mistake somewhere?

Hi
You should use an amd64 kernel for dual core processors, i think, not an
SMP one.

2x32 != 64 ;)
Does mobile Core Duo have emt64?

rt-kernel has heavily reworked irq handling and seems to have issues
with acpi and laptops.
On my laptop (acer 3004wtmi, Sonoma 2ghz), rt-kernels boots, but
harddrive crawls. Passing acpi=off to kernel solves this, but makes
nearly all devices use 2 or 3 interrupts (bad).
Try turning acpi off in rt-kernel. You'll loose battery info, but it
may boot at least.

oh, sorry. i thought it would be the same as with the pentium d, which
apparently isn't the case.

Thank you, now the kernel boots!
I can live without battery monitoring but it breaks the network
interface. And this is a little annoying...

Breaks? You said it does not even boot with acpi=on :)
But possibly, acpi=off is the problem here, because I just remembered,
with it my internal sound card does not work.
I'm afraid no quick solution here. We have to wait. But it would be
great if we can help Ingo and others to resolve all this problems.
If somebody (Lee?) can help us with advice, how can we efficiently
communicate with Ingo and other developers, as they are very busy, I
suppose, and lkml has very high traffic.
