Please apply the appended patch and then try: # echo 8 > /proc/sys/kernel/printk # echo 5 > /sys/power/pm_test_level # echo mem > /sys/power/state (should wait for approx. 3 sec. and return to the boot prompt) # echo 4 > /sys/power/pm_test_level # echo mem > /sys/power/state (should wait for approx. 3 sec. and return to the boot prompt) ... # echo 1 > /sys/power/pm_test_level # echo mem > /sys/power/state (should wait for approx. 3 sec. and return to the boot prompt) and see if you can reproduce the problem and for which test level. [Echoing 0 to /sys/power/pm_test_level restores the normal behavior.] Greetings, Rafael --- kernel/power/main.c | 75 ++++++++++++++++++++++++++++++++++++++++++++------- kernel/power/power.h | 10 ++++++ 2 files changed, 76 insertions(+), 9 deletions(-) Index: linux-2.6/kernel/power/main.c =================================================================== --- linux-2.6.orig/kernel/power/main.c +++ linux-2.6/kernel/power/main.c @@ -28,6 +28,46 @@ BLOCKING_NOTIFIER_HEAD(pm_chain_head); DEFINE_MUTEX(pm_mutex); +#ifdef CONFIG_PM_DEBUG +int pm_test_level = TEST_NONE; + +static int suspend_test(int level) +{ + if (pm_test_level == level) { + printk(KERN_INFO "suspend debug: Waiting for 3 seconds.\n"); + mdelay(3000); + return 1; + } + return 0; +} + +static ssize_t pm_test_level_show(struct kset *kset, char *buf) +{ + return sprintf(buf, "%d\n", pm_test_level); +} + +static ssize_t +pm_test_level_store(struct kset *kset, const char *buf, size_t n) +{ + int val; + + if (sscanf(buf, "%d", &val) != 1) + return -EINVAL; + + if (val < TEST_NONE || val > TEST_FREEZER) + return -EINVAL; + + pm_test_level = val; + + return n; +} + +power_attr(pm_test_level); +#else /* !CONFIG_PM_DEBUG */ +static inline int suspend_test(int level) { return 0; } +#endif /* !CONFIG_PM_DEBUG */ + + #ifdef CONFIG_SUSPEND /* This is just an arbitrary number */ @@ -133,7 +173,10 @@ static int suspend_enter(suspend_state_t printk(KERN_ERR "Some devices failed to power down\n"); goto Done; } - error = suspend_ops->enter(state); + + if (!suspend_test(TEST_CORE)) + error = suspend_ops->enter(state); + device_power_up(); Done: arch_suspend_enable_irqs(); @@ -164,16 +207,25 @@ int suspend_devices_and_enter(suspend_st printk(KERN_ERR "Some devices failed to suspend\n"); goto Resume_console; } + + if (suspend_test(TEST_DEVICES)) + goto Resume_devices; + if (suspend_ops->prepare) { error = suspend_ops->prepare(); if (error) goto Resume_devices; } + + if (suspend_test(TEST_PLATFORM)) + goto Finish; + error = disable_nonboot_cpus(); - if (!error) + if (!error && !suspend_test(TEST_CPUS)) suspend_enter(state); enable_nonboot_cpus(); + Finish: if (suspend_ops->finish) suspend_ops->finish(); Resume_devices: @@ -240,12 +292,17 @@ static int enter_state(suspend_state_t s printk("done.\n"); pr_debug("PM: Preparing system for %s sleep\n", pm_states[state]); - if ((error = suspend_prepare())) + error = suspend_prepare(); + if (error) goto Unlock; + if (suspend_test(TEST_FREEZER)) + goto Finish; + pr_debug("PM: Entering %s sleep\n", pm_states[state]); error = suspend_devices_and_enter(state); + Finish: pr_debug("PM: Finishing wakeup.\n"); suspend_finish(); Unlock: @@ -363,18 +420,18 @@ pm_trace_store(struct kset *kset, const } power_attr(pm_trace); +#endif /* CONFIG_PM_TRACE */ static struct attribute * g[] = { &state_attr.attr, +#ifdef CONFIG_PM_TRACE &pm_trace_attr.attr, +#endif +#ifdef CONFIG_PM_DEBUG + &pm_test_level_attr.attr, +#endif NULL, }; -#else -static struct attribute * g[] = { - &state_attr.attr, - NULL, -}; -#endif /* CONFIG_PM_TRACE */ static struct attribute_group attr_group = { .attrs = g, Index: linux-2.6/kernel/power/power.h =================================================================== --- linux-2.6.orig/kernel/power/power.h +++ linux-2.6/kernel/power/power.h @@ -211,3 +211,13 @@ static inline int pm_notifier_call_chain return (blocking_notifier_call_chain(&pm_chain_head, val, NULL) == NOTIFY_BAD) ? -EINVAL : 0; } + +/* Suspend test levels */ +enum { + TEST_NONE, + TEST_CORE, + TEST_CPUS, + TEST_PLATFORM, + TEST_DEVICES, + TEST_FREEZER +}; _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
