Dear ACPI team, One of our customer gets a very high CPU usage because of many interrupts reported on /sys/firmware/acpi/interrupts/gpe03 I've dumped the ACPI and disassembled the ACPI tables but I'm unable to find something obviously related to gpe03 in these tables. I'had a look to drivers/acpi/sysfs.c and related kernel sources files in the hope to understand any possible link between gpe03 and some ACPI definition but at the end I'm lost in space. Could you give me some tips or point me to some helpful document to point me to the faulty hardware pin or device ? Thanks very much for help Gilles Buloz Kontron Modular Computers
