Subject: 2.4.22 hangs upon echo > /proc/acpi/alarm
Date: Wed, 12 Nov 2003 20:33:18 +0800	[thread overview]
Message-ID: <200311122033.18729.mhf@linuxmail.org> (raw)

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
