Description Gustavo Michels 2003-12-12 21:50:34 UTC

Distribution: Gentoo Linux
Hardware Environment: Laptop HP Pavilion ze4430us

Problem Description: Kernel hangs with message "ACPI: IRQ9 SCI: Level Trigger". 
Only bootable if acpi=off is passed as option. I applied the latest patch 
available (acpi-20031203-2.6.0-test11.diff.bz2) with the same results.

I tried pci=noacpi and noapic also, no luck.

Also tried 2.6.0.test10-mm1, same thing.

try acpi_pic_sci=level, please

Comment 7 Len Brown 2003-12-15 09:07:17 UTC

Does it still fail if you boot with pci=noacpi? 
 
> ACPI: IRQ9 SCI: Level Trigger 
This means that the kernel found IRQ 9 already set to level triggered, 
so "acpi_pic_sci=level" should not have any effect.  (acpi_pic_sci=edge may effect 
the problem, but there is no indication that it is the right thing to do) 
 
Seems more like we're getting some sort of event before we're ready -- should 
be able to confirm by enabling debugging output.

patch to enable verbose3 messages

Please apply this patch to enable verbose debugging and report the last thing
it prints before the hang.

thanks,

I am currently compiling KDE so currently I can't give you results for the tests 
you asked.

I can add one thing: ACPI works if I disable Local APIC support on uniprocessors 
and IO-APIC support on uniprocessors on a test11 kernel (unpatched).

I'll come back when KDE finishes so I can send your test results.

Comment 10 Gustavo Michels 2003-12-15 14:07:17 UTC

Hi guys

I patched the kernel as you asked but I get no debug messages. I am using the 
plain test11 source (I didn't apply the latest patch available at SF) and I 
don't get that SCI message anymore. Now all I get is "spurious 8259A interrupt: 
IRQ7." right after "ACPI: Subsystem revision 20031002" and it hangs.

That "acpi_pic_sci=level" didn't change anything. Also pci=noacpi produces the 
same problem.

I'll try to get a serial console so I can put the entries here.

Identical to

http://bugzilla.kernel.org/show_bug.cgi?id=1774

? Fixed there...

please re-open if the patch in bug #1269 does not address the problem.

thanks,

Yes, the patch in bug #1269 solved the problem. Now running 2.6.1 with APIC and 
IO-APIC.
