Hi, I have set up a script that cycles my system through hibernation, because I am tired of 90% of time working suspend to disk. I also set up the kernel to log directly into video memory which happens to be preserved during reboots. One bug is already fixed (I posted about it on linux-wireless) Here is another bug: <3>[ 360.670152] INFO: task tee:3466 blocked for more than 120 seconds. <3>[ 360.670469] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. <6>[ 360.670859] tee D 0000000000000000 0 3466 3320 0x00000000 <3>[ 360.671386] BUG: using smp_processor_id() in preemptible [00000000] code: khungtaskd/354 <4>[ 360.671783] caller is show_stack_log_lvl+0x32/0x170 <4>[ 360.672053] Pid: 354, comm: khungtaskd Not tainted 2.6.32-rc7-wl #192 <4>[ 360.672373] Call Trace: <4>[ 360.672554] [<ffffffff811e212b>] debug_smp_processor_id+0xcb/0xe0 <4>[ 360.672869] [<ffffffff8100f282>] show_stack_log_lvl+0x32/0x170 <4>[ 360.673172] [<ffffffff8139212d>] ? printk+0x3c/0x3f <4>[ 360.673440] [<ffffffff81010977>] show_stack+0x17/0x20 <4>[ 360.673705] [<ffffffff8103c8b2>] sched_show_task+0x92/0x100 <4>[ 360.673991] [<ffffffff8108696d>] watchdog+0x27d/0x2e0 <4>[ 360.674253] [<ffffffff8108675d>] ? watchdog+0x6d/0x2e0 <4>[ 360.674527] [<ffffffff810866f0>] ? watchdog+0x0/0x2e0 <4>[ 360.674792] [<ffffffff8105bb0e>] kthread+0x8e/0xa0 <4>[ 360.675047] [<ffffffff8100cf1a>] child_rip+0xa/0x20 <4>[ 360.675309] [<ffffffff8100c880>] ? restore_args+0x0/0x30 <4>[ 360.675582] [<ffffffff8105ba80>] ? kthread+0x0/0xa0 <4>[ 360.675840] [<ffffffff8100cf10>] ? child_rip+0x0/0x20 <4>[ 360.676100] ffff88007de137b8 0000000000000046 0000000000000000 0000000000000002 <4>[ 360.676725] ffff88007de137f8 0000000000000000 ffff880002213c18 0000000000000002 <4>[ 360.677353] ffff88000220efc8 00000000ffffcae7 ffff88007e6402b8 ffff88007de13fd8 <4>[ 360.677987] Call Trace: <4>[ 360.678159] [<ffffffff813934c5>] schedule_timeout+0x205/0x270 <4>[ 360.678458] [<ffffffff8106cf7b>] ? mark_held_locks+0x6b/0xa0 <4>[ 360.678742] [<ffffffff81395b6b>] ? _spin_unlock_irq+0x2b/0x60 <4>[ 360.679030] [<ffffffff8106d275>] ? trace_hardirqs_on_caller+0x145/0x190 <4>[ 360.679348] [<ffffffff81394b8d>] __down_timeout+0x6d/0xb0 <4>[ 360.679632] [<ffffffff810608ff>] ? down_timeout+0x1f/0x60 <4>[ 360.679908] [<ffffffff81060938>] down_timeout+0x58/0x60 <4>[ 360.680229] [<ffffffff81211dfc>] acpi_os_wait_semaphore+0x49/0x57 <4>[ 360.680545] [<ffffffff81225b5e>] acpi_ex_system_wait_semaphore+0x3c/0x4f <4>[ 360.680875] [<ffffffff8122070d>] acpi_ev_acquire_global_lock+0xbf/0xc3 <4>[ 360.681190] [<ffffffff8122772c>] acpi_ex_acquire_mutex_object+0x39/0x63 <4>[ 360.681513] [<ffffffff812273a8>] acpi_ex_acquire_global_lock+0x24/0x46 <4>[ 360.681828] [<ffffffff81222e46>] acpi_ex_read_data_from_field+0x121/0x16f <4>[ 360.682154] [<ffffffff8106d2cd>] ? trace_hardirqs_on+0xd/0x10 <4>[ 360.682444] [<ffffffff81227c40>] acpi_ex_resolve_node_to_value+0x18c/0x218 <4>[ 360.682780] [<ffffffff8122388f>] acpi_ex_resolve_to_value+0x203/0x20c <4>[ 360.683104] [<ffffffff8121de8d>] acpi_ds_evaluate_name_path+0x79/0xf5 <4>[ 360.683438] [<ffffffff8121cb0c>] acpi_ds_exec_end_op+0x96/0x3d6 <4>[ 360.683732] [<ffffffff8122e4c7>] acpi_ps_parse_loop+0x7bb/0x940 <4>[ 360.684026] [<ffffffff8122d5d1>] acpi_ps_parse_aml+0x9a/0x2d9 <4>[ 360.684314] [<ffffffff8122ece2>] acpi_ps_execute_method+0x1e4/0x2b6 <4>[ 360.684625] [<ffffffff8122a635>] acpi_ns_evaluate+0xe1/0x1a8 <4>[ 360.684909] [<ffffffff8122a08d>] acpi_evaluate_object+0x13d/0x236 <4>[ 360.685211] [<ffffffff812126cf>] acpi_evaluate_integer+0x2f/0x4d <4>[ 360.685509] [<ffffffff8106cf7b>] ? mark_held_locks+0x6b/0xa0 <4>[ 360.685794] [<ffffffff81213785>] acpi_bus_get_status_handle+0x1d/0x33 <4>[ 360.686106] [<ffffffff812137b4>] acpi_bus_get_status+0x19/0x34 <4>[ 360.686400] [<ffffffff8123aa32>] acpi_battery_update+0x1e/0x24d <4>[ 360.686693] [<ffffffff8106d2cd>] ? trace_hardirqs_on+0xd/0x10 <4>[ 360.686980] [<ffffffff81395bdd>] ? _spin_unlock_irqrestore+0x3d/0x80 <4>[ 360.687289] [<ffffffff8123acf8>] acpi_battery_resume+0x25/0x29 <4>[ 360.687578] [<ffffffff81214004>] acpi_device_resume+0x25/0x2b <4>[ 360.687867] [<ffffffff8126944a>] dpm_resume_end+0x4aa/0x500 <4>[ 360.688152] [<ffffffff8107d8f9>] hibernation_snapshot+0xc9/0x280 <4>[ 360.688449] [<ffffffff8107db9d>] hibernate+0xed/0x1f0 <4>[ 360.688712] [<ffffffff8107c3ac>] state_store+0xec/0x100 <4>[ 360.688985] [<ffffffff811d5777>] kobj_attr_store+0x17/0x20 <4>[ 360.689266] [<ffffffff811355f4>] sysfs_write_file+0xd4/0x150 <4>[ 360.689555] [<ffffffff810d1a08>] vfs_write+0xb8/0x1a0 <4>[ 360.689819] [<ffffffff810d1bcc>] sys_write+0x4c/0x80 <4>[ 360.690117] [<ffffffff8100beab>] system_call_fastpath+0x16/0x1b <4>[ 360.690431] 2 locks held by tee/3466: I attach the dmesg (copied from video ram) too. and acpidump output.
