This seems to be an userspace only problem and is not related to any kernel driver: amarok and/or audacious seems to repeatedly read/write to the X socket: tail of the strace of audacious: gettimeofday({1177782978, 24491}, NULL) = 0 clock_gettime(CLOCK_MONOTONIC, {224, 581502867}) = 0 clock_gettime(CLOCK_MONOTONIC, {224, 581614815}) = 0 select(4, [3], [3], NULL, NULL) = 1 (out [3]) writev(3, [{"\221\3\n\0\3\0\200\2#\0\200\2\0\6@\0\240\4\20\0L\0\20\0"..., 40}], 1) = 40 read(3, 0x80da6c8, 4096) = -1 EAGAIN (Resource temporarily unavailable) gettimeofday({1177782978, 25286}, NULL) = 0 poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 9) = 0 gettimeofday({1177782978, 33242}, NULL) = 0 read(3, 0x80da6c8, 4096) = -1 EAGAIN (Resource temporarily unavailable) gettimeofday({1177782978, 33475}, NULL) = 0 poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 1) = 0 gettimeofday({1177782978, 36548}, NULL) = 0 clock_gettime(CLOCK_MONOTONIC, {224, 593554129}) = 0 read(3, 0x80da6c8, 4096) = -1 EAGAIN (Resource temporarily unavailable) gettimeofday({1177782978, 36921}, NULL) = 0 poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 9) = 0 gettimeofday({1177782978, 46572}, NULL) = 0 clock_gettime(CLOCK_MONOTONIC, {224, 603578038}) = 0 clock_gettime(CLOCK_MONOTONIC, {224, 603689148}) = 0 select(4, [3], [3], NULL, NULL) = 1 (out [3]) writev(3, [{"\221\3\n\0\3\0\200\2#\0\200\2\0\6@\0\0\4 \0L\0\20\0\23"..., 40}], 1) = 40 read(3, 0x80da6c8, 4096) = -1 EAGAIN (Resource temporarily unavailable) gettimeofday({1177782978, 47341}, NULL) = 0 poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 9) = 0 gettimeofday({1177782978, 56566}, NULL) = 0 read(3, 0x80da6c8, 4096) = -1 EAGAIN (Resource temporarily unavailable) gettimeofday({1177782978, 56799}, NULL) = 0 poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 0) = 0 clock_gettime(CLOCK_MONOTONIC, {224, 613921380}) = 0 read(3, 0x80da6c8, 4096) = -1 EAGAIN (Resource temporarily unavailable) gettimeofday({1177782978, 57282}, NULL) = 0 poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 9) = 0 gettimeofday({1177782978, 67696}, NULL) = 0 clock_gettime(CLOCK_MONOTONIC, {224, 624704202}) = 0 clock_gettime(CLOCK_MONOTONIC, {224, 624817966}) = 0 select(4, [3], [3], NULL, NULL) = 1 (out [3]) writev(3, [{"\221\3\n\0\3\0\200\2#\0\200\2\0\6@\0P\4 \0L\0\20\0\23\0"..., 40}], 1) = 40 read(3, 0x80da6c8, 4096) = -1 EAGAIN (Resource temporarily unavailable) gettimeofday({1177782978, 68476}, NULL) = 0 poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 9) = 0 gettimeofday({1177782978, 76564}, NULL) = 0 read(3, 0x80da6c8, 4096) = -1 EAGAIN (Resource temporarily unavailable) gettimeofday({1177782978, 76796}, NULL) = 0 poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 0) = 0 clock_gettime(CLOCK_MONOTONIC, {224, 633919963}) = 0 read(3, 0x80da6c8, 4096) = -1 EAGAIN (Resource temporarily unavailable) gettimeofday({1177782978, 77280}, NULL) = 0 poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}], 2, 9) = 0 gettimeofday({1177782978, 86898}, NULL) = 0 clock_gettime(CLOCK_MONOTONIC, {224, 643911329}) = 0 clock_gettime(CLOCK_MONOTONIC, {224, 644025581}) = 0 select(4, [3], [3], NULL, NULL) = 1 (out [3]) writev(3, [{"\221\3\n\0\3\0\200\2#\0\200\2\0\6@\0\240\4 \0L\0\20\0\23"..., 40}], 1) = 40 read(3, 0x80da6c8, 4096) = -1 EAGAIN (Resource temporarily unavailable) gettimeofday({1177782978, 87702}, NULL) = 0 poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN, revents=POLLIN}], 2, 9) = 1 read(3, "\n\3P\v\4\0\200\2\0\0\0\0\210v\274\277r\300\10\10x\35!"..., 4096) = 96 read(3, 0x80da6c8, 4096) = -1 EAGAIN (Resource temporarily unavailable) read(3, 0x80da6c8, 4096) = -1 EAGAIN (Resource temporarily unavailable) read(3, 0x80da6c8, 4096) = -1 EAGAIN (Resource temporarily unavailable) gettimeofday({1177782978, 90108}, NULL) = 0 gettimeofday({1177782978, 90163}, NULL) = 0 But i didn't have a look at what is going on here. But running amarok and/or audacious (without playing a song!) adds 50-70 more interrupts to the timer interrupt. with kind regards thomas - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
