ACPI version is 20031002
Initial backtrace obtained with kdb:
acpi_os_read_port+36 acpi_hw_lowlevel_read+7b acpi_ev_gpe_detect+94 acpi_ev_sci_xrupt_handler+3c acpi_irq+d handle_IRQ_event+31 do_IRQ+72 call_do_IRQ+5 do_softirq+5a do_IRQ+a1 proc_file_write+9b sys_write+be system_call+33
Further stepping shows endless loop around:
acpi_ev_gpe_detect+80 acpi_hw_lowlevel_read acpi_os_read_port acpi_ut_get_region_name acpi_ut_debug_print acpi_ut_debug_print jmp acpi_ev_gpe_detect+80
Debugging is compiled in, but no meesages go to dmesg
How to enable acpi_ut_debug_print output?
Regards Michael
