Subject: 2.6.25-current-git hangs on boot

Hi,

trying out newest git, I see a hang with
ACPI: SSDT 7feb9c10, 02ae (r1 APPLE CPU0Ist 3000 intl 20050309)
ACPI: SSDT 7feb9910, 02c3 (r1 APPLE CPU0Cst 3001 intl 20050309)
...
ACPI: Processor [CPU0] (supports 8 throttling states)
ACPI: SSDT 7feb9f10, 0087 (r1 APPLE CPU1Ist 3000 intl 20050309)
ACPI: SSDT 7feb8f10, 0085 (r1 APPLE CPU1Cst 3001 intl 20050309)
...
ACPI: ACPI0007:01 is registered as cooling_device1
ACPI: Processor [CPU1] (supports 8 throttling states)

as the last message...

Any ideas?
Soeren

the pci=nommconf kernel parameter helped it?

yes indeed, this switch reliably helps to over come the hang at *this
stage* (I tried booting with booth the switch and w/o).

however with 50% chance I still see a hang directly after

cpuidle: using governor ladder

note that I've never seen these hangs on 2.6.24* ...

Do you have CONFIG_CPU_IDLE set? If you have, please try to unset it and
retest.

Thanks,

Yes I had. When disabling that option booting 10 times in a row worked
without problems.

Rafael,

I am looking at the CPU_IDLE part of this regression. Just want to note
that there is another regression with needing pci=nommconf in current
git which was not required in .24. I am not sure whether you are already
tracking that as a different issue.

Thanks,
Venki

I've noticed the thread, but I haven't created a Bugzilla entry for it yet.

Thanks for the information anyway. :-)
