Re: No events when pressing power button

Hi Andy,

great, another ACPI problem/mystery solved! We are making progress!

Now that we found out that calling eisa_set_level_irq(ACPI_IRQ_NUMBER)
does turn on ACPI event reporting for some machines, would you please
include this call into the ACPI patch proper?

I am really looking forward to the current ACPI implementation making
it into the 2.4 kernel baseline!

Thank you very much for your ongoing efforts!

Arndt

The problem *may* be that the ACPI interrupt is not being set to
active-low, level-triggered properly (we do this for PCI irqs but not
our own ;-)

Is your acpi interrupt shared with any PCI devices? If the above
hypothesis is true, the answer should be "no".

I don't know about people's comfort level with the code, but you might try
adding a call to eisa_set_level_irq(<ACPI irq #>) and seeing if that gets
interrupts happening properly.

I own one of those machines that need eisa_set_level_irq() for some
builtin devices, and I have never seen any events coming out of
/var/log/acpid so far. The ACPI interrupt is not shared with anything.

So I really guess you are right and eisa_set_level_irq(9) might be
needed to turn ACPI interrupt reporting on. I'll add this call next
time I build a kernel.

[The machine is a Gericom 1st Supersonic M6-T (FIC A380 OEM).]

It works on my Gericom M6T. I have added "eisa_set_level_irq(9);" in the 
pci_irq.c at line 365.
Now I get events from LID, Powerbutton and I can even use the special 
function keys to set the backlight :-)
