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
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.
Created attachment 1667 [details] patch to enable verbose3 messages Please apply this patch to enable verbose debugging and report the last thing it prints before the hang. thanks, -Len
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.
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, -Len *** This bug has been marked as a duplicate of 1269 ***
Yes, the patch in bug #1269 solved the problem. Now running 2.6.1 with APIC and IO-APIC.
