Hi, I just booted from 2.6.36 (without PM debugging configured) into 2.6.37-rc5 (with PM debugging enabled). There is endless log spam like this: Dec 11 17:11:31 stein kernel: scsi host6: rpm_resume flags 0x4 Dec 11 17:11:31 stein kernel: scsi host6: rpm_resume returns 1 Dec 11 17:11:31 stein kernel: scsi host6: rpm_resume flags 0x4 Dec 11 17:11:31 stein kernel: scsi host6: rpm_resume returns 1 Dec 11 17:11:31 stein kernel: scsi host6: rpm_resume flags 0x4 Dec 11 17:11:31 stein kernel: scsi host6: rpm_resume returns 1 Dec 11 17:11:33 stein kernel: scsi host6: rpm_resume flags 0x4 Dec 11 17:11:33 stein kernel: scsi host6: rpm_resume returns 1 Dec 11 17:11:33 stein kernel: scsi host6: rpm_resume flags 0x4 Dec 11 17:11:33 stein kernel: scsi host6: rpm_resume returns 1 Dec 11 17:11:33 stein kernel: scsi host6: rpm_resume flags 0x4 Dec 11 17:11:33 stein kernel: scsi host6: rpm_resume returns 1 Dec 11 17:11:33 stein kernel: scsi host6: rpm_resume flags 0x4 Dec 11 17:11:33 stein kernel: scsi host6: rpm_resume returns 1 Dec 11 17:11:33 stein kernel: scsi host6: rpm_resume flags 0x4 Dec 11 17:11:33 stein kernel: scsi host6: rpm_resume returns 1 Dec 11 17:11:33 stein kernel: scsi host6: rpm_resume flags 0x4 Dec 11 17:11:33 stein kernel: scsi host6: rpm_resume returns 1 Dec 11 17:11:35 stein kernel: scsi host6: rpm_resume flags 0x4 Dec 11 17:11:35 stein kernel: scsi host6: rpm_resume returns 1 Dec 11 17:11:35 stein kernel: scsi host6: rpm_resume flags 0x4 Dec 11 17:11:35 stein kernel: scsi host6: rpm_resume returns 1 Dec 11 17:11:35 stein kernel: scsi host6: rpm_resume flags 0x4 Dec 11 17:11:35 stein kernel: scsi host6: rpm_resume returns 1 Dec 11 17:11:35 stein kernel: scsi host6: rpm_resume flags 0x4 Dec 11 17:11:35 stein kernel: scsi host6: rpm_resume returns 1 Dec 11 17:11:35 stein kernel: scsi host6: rpm_resume flags 0x4 Dec 11 17:11:35 stein kernel: scsi host6: rpm_resume returns 1 Dec 11 17:11:35 stein kernel: scsi host6: rpm_resume flags 0x4 Dec 11 17:11:35 stein kernel: scsi host6: rpm_resume returns 1 Dec 11 17:11:37 stein kernel: scsi host6: rpm_resume flags 0x4 Dec 11 17:11:37 stein kernel: scsi host6: rpm_resume returns 1 Dec 11 17:11:37 stein kernel: scsi host6: rpm_resume flags 0x4 Dec 11 17:11:37 stein kernel: scsi host6: rpm_resume returns 1 Dec 11 17:11:37 stein kernel: scsi host6: rpm_resume flags 0x4 Dec 11 17:11:37 stein kernel: scsi host6: rpm_resume returns 1 Why is rpm_resume performed 6 times every two seconds? host6 is pata_atiixp with an: 00:14.1 IDE interface: ATI Technologies Inc SB700/SB800 IDE Controller (prog-if 8a [Master SecP PriP]) # grep . /sys/class/scsi_host/host6/power/* /sys/class/scsi_host/host6/power/async:enabled grep: /sys/class/scsi_host/host6/power/autosuspend_delay_ms: Input/output error /sys/class/scsi_host/host6/power/control:auto /sys/class/scsi_host/host6/power/runtime_active_kids:0 /sys/class/scsi_host/host6/power/runtime_active_time:0 /sys/class/scsi_host/host6/power/runtime_enabled:disabled /sys/class/scsi_host/host6/power/runtime_status:unsupported /sys/class/scsi_host/host6/power/runtime_suspended_time:0 /sys/class/scsi_host/host6/power/runtime_usage:0 Attached to it is one device: Host: scsi6 Channel: 00 Id: 00 Lun: 00 Vendor: PLEXTOR Model: DVD-ROM PX-130A Rev: 1.01 Type: CD-ROM ANSI SCSI revision: 05 # grep . /sys/class/scsi_host/host6/device/target6\:0\:0/6\:0\:0\:0/power/* /sys/class/scsi_host/host6/device/target6:0:0/6:0:0:0/power/async:enabled grep: /sys/class/scsi_host/host6/device/target6:0:0/6:0:0:0/power/autosuspend_delay_ms: Input/output error /sys/class/scsi_host/host6/device/target6:0:0/6:0:0:0/power/control:on /sys/class/scsi_host/host6/device/target6:0:0/6:0:0:0/power/runtime_active_kids:0 /sys/class/scsi_host/host6/device/target6:0:0/6:0:0:0/power/runtime_active_time:2689146 /sys/class/scsi_host/host6/device/target6:0:0/6:0:0:0/power/runtime_enabled:forbidden /sys/class/scsi_host/host6/device/target6:0:0/6:0:0:0/power/runtime_status:active /sys/class/scsi_host/host6/device/target6:0:0/6:0:0:0/power/runtime_suspended_time:0 /sys/class/scsi_host/host6/device/target6:0:0/6:0:0:0/power/runtime_usage:2 -- Stefan Richter -=====-==-=- ==-- -=-== http://arcgraph.de/sr/ _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
