--- Comment #6 from Ali Gholami Rudi <aliqr...@gmail.com> 2010-02-18 15:14:21 --- Hi Alexey, Now I see kacpi_notify high cpu usage again. I think the reason is now I use the machine in a warmer environment than the last few weeks. The cpu temperature update delay still exists: the reported temperature remains constant after boot until it reaches acpi active cooling thermal zone. As you suggested, I've added gpe_number to printk messages and added a msleep(10) call in acpi_ev_asynch_execute_gpe_method(). I see a lot of included messages. kacpi_notify cpu usage has decreased to 10-20% (I think due to the msleep() call). Thanks, Ali === gpe_number debug messages ==== [ 6529.162788] acpi_ev_notify_dispatch [ 6529.168096] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.168177] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.168547] acpi_ev_notify_dispatch [ 6529.170921] acpi_ev_notify_dispatch [ 6529.179067] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.187114] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.187479] acpi_ev_notify_dispatch [ 6529.192863] acpi_ev_notify_dispatch [ 6529.198095] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.198175] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.198547] acpi_ev_notify_dispatch [ 6529.209081] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.209123] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.209484] acpi_ev_notify_dispatch [ 6529.214917] acpi_ev_notify_dispatch [ 6529.220082] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.247565] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.247932] acpi_ev_notify_dispatch [ 6529.254050] acpi_ev_notify_dispatch [ 6529.259041] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.259087] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.259447] acpi_ev_notify_dispatch [ 6529.261819] acpi_ev_notify_dispatch [ 6529.270082] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.308007] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.308383] acpi_ev_notify_dispatch [ 6529.314198] acpi_ev_notify_dispatch [ 6529.319189] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.319236] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.319598] acpi_ev_notify_dispatch [ 6529.321966] acpi_ev_notify_dispatch [ 6529.330082] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.619435] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.619803] acpi_ev_notify_dispatch [ 6529.625930] acpi_ev_notify_dispatch [ 6529.630965] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.631054] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.631418] acpi_ev_notify_dispatch [ 6529.633790] acpi_ev_notify_dispatch [ 6529.642083] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.661485] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.661850] acpi_ev_notify_dispatch [ 6529.667065] acpi_ev_notify_dispatch [ 6529.672066] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.672112] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.672473] acpi_ev_notify_dispatch [ 6529.674840] acpi_ev_notify_dispatch [ 6529.683067] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.694340] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.694704] acpi_ev_notify_dispatch [ 6529.700126] acpi_ev_notify_dispatch [ 6529.705170] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.705214] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.705575] acpi_ev_notify_dispatch [ 6529.707946] acpi_ev_notify_dispatch [ 6529.716081] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.767924] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.768311] acpi_ev_notify_dispatch [ 6529.774284] acpi_ev_notify_dispatch [ 6529.779274] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.779330] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.779691] acpi_ev_notify_dispatch [ 6529.782081] acpi_ev_notify_dispatch [ 6529.790081] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.790126] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.790489] acpi_ev_notify_dispatch [ 6529.801066] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.838882] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.839272] acpi_ev_notify_dispatch [ 6529.844494] acpi_ev_notify_dispatch [ 6529.850057] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.850135] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.850509] acpi_ev_notify_dispatch [ 6529.852883] acpi_ev_notify_dispatch [ 6529.861066] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.867786] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.868167] acpi_ev_notify_dispatch [ 6529.873553] acpi_ev_notify_dispatch [ 6529.879095] acpi_ev_asynch_enable_gpe gpe=2 [ 6529.879174] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6529.879545] acpi_ev_notify_dispatch [ 6529.881915] acpi_ev_notify_dispatch [ 6529.890066] acpi_ev_asynch_enable_gpe gpe=2 [ 6530.079347] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6530.079718] acpi_ev_notify_dispatch [ 6530.085094] acpi_ev_notify_dispatch [ 6530.090116] acpi_ev_asynch_enable_gpe gpe=2 [ 6530.090159] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6530.090519] acpi_ev_notify_dispatch [ 6530.092886] acpi_ev_notify_dispatch [ 6530.101082] acpi_ev_asynch_enable_gpe gpe=2 [ 6530.108256] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6530.108622] acpi_ev_notify_dispatch [ 6530.114163] acpi_ev_notify_dispatch [ 6530.119165] acpi_ev_asynch_enable_gpe gpe=2 [ 6530.119212] acpi_ev_asynch_execute_gpe_method: gpe=2 [ 6530.119572] acpi_ev_notify_dispatch [ 6530.121943] acpi_ev_notify_dispatch [ 6530.130066] acpi_ev_asynch_enable_gpe gpe=2 -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
