Well, for a start, disable MSI for now (pci=nomsi on the kernel command

In the nosmp boot, something seems amiss with interrupt routing.  nomsi may
help there as well, but I'll need to have a closer look at the code to work
out what's really going wrong here.  Hm, its probably:
[    0.000000] ACPI: Skipping IOAPIC probe due to 'noapic' option.

I guess nosmp implies noapic?  Anyway, we don't do well without ioapics at
present...

The pci=nomsi helped a lot.

I have booting (at least almost)

Again two logs attached. This time the without nosmp does better.

Gets to a checking battery state line then it seems to stop.

What normally happens next? Looks like its pretty close to the end of the boot sequence; is that where it would normally print the login prompt? Is the machine on the network at that point? Can you log in remotely?

The nosmp does the same as last time, a initramfs prompt followed by
ATA trying...

Yes, that's going to be non-functional; none of the hardware interrupts have been set up properly, so none of the drivers are going to see the interrupts they're expecting.

I will try to disable some of the init scripts or try single user mode to
see if I can get a normal prompt.

I think it might just be a matter of getting your devices set up properly or something.

Might not have much time to work on it over the next couple days...

Thanks for testing this.  Your logs have lots of valuable stuff in them.
