And I found this new message appearing in 2.4.28: ACPI: IRQ9 SCI: Edge set to Level Trigger. Weird since IRQ 9 is not in use in this system. IRQ9 is typically used by ACPI. After some digging in the sources, I found that the newly introduced (2.4.28-rc2) function acpi_early_init() runs wether or not acpi=off was specified on the command line. This trivial patch makes my laptop suspend-happy. Len, please confirm that this is ok. Marcelo, please include in 29-pre. Phil.
