No luck getting 2.6.x kernel to work with ACPI on compaq laptop

No luck getting 2.6.x kernel to work with ACPI on compaq laptop

[Danny ter Haar]

My Compaq presario 700EA locks up dead during boot with
ACPI enabled. With bootoption acpi=off (or not compiled into the kernel)
the machine works just fine.

I put on acpi debug and typed over by hand (laptop's dont have serial
ports these days anymore) :

ACPI: Subsystem revision 20040326
tbxface-0017[03] acpi_load_tables: ACPI tables succesfully acquired
Parsing all Control Methods: [......]
Table [DSDT] (id F005) - 433 Objects with 44 Devices 109 Methods 15
Regions
Parsing all Control Methods: 
Table [SSDT] (id f003) - 3 objects with 0 Devices 0 Methods 0 Regions
ACPI: IRQ10 SCI: Edge set to level trigger

After this the machine is dead in the water.
No magic sysrq or anything.

Any ideas how to solve this issue ?
I googled around a bit but found nothing usefull.
I upgraded bios to latest available from compaq, with no different
results.

Help/suggestions appreciated.

It sounds as if some driver is using IRQ10, and that another device
is also on that IRQ. This will create an interrupt storm the moment
you switch the triggering from edge to level....

So: Which devices use IRQ10 when the computer works?

Len Brown from Intel sent me :

"try booting with "nolapic" (or disable LOCAL_APIC in the kernel build)"

That indeed solved my problem, i can now use poweroff etc.
I will add a bugreport to http://bugzilla.kernel.org/show_bug.cgi?id=1682
l8er this week ;-)
