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
