Hello,
in recent kernel (latest tried 2.6.17-rc1-git5) if I do suspend to disk and then
suspend to ram, then system freezes. Using sysrq-P I found that it gets stuck
(endless loop) in ACPI code:
syscall_call
sys_write
vfs_write
sysfs_write_file
state_store
enter_state
acpi_sleep_prepare
acpi_enable_wakeup_device_prep
acpi_enter_sleep_state_prep
acpi_evaluate_object
acpi_ns_evaluate_by_name
acpi_ns_evaluate_by_handle
acpi_ps_execute_method
acpi_ps_execute_pass
acpi_ps_parse_aml
acpi_ps_parse_loop
------------------ (from this line functions change while repeating sysrq-P)
(acpi_ds_exec_end_op
acpi_ds_create_operands
acpi_ds_create_operand)
OR
(acpi_ds_result_stack_push)
OR
(acpi_ds_exec_end_op
acpi_ex_resolve_operands
acpi_ex_resolve_to_value
acpi_ex_resolve_node_to_value
acpi_ex_read_data_from_field
acpi_ut_create_internal_object_dbg
acpi_ut_allocate_object_desc_dbg)
