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
