https://bugzilla.kernel.org/show_bug.cgi?id=20112 Summary: dmesg spam: "scsi host5: __pm_runtime_resume() returns 1" (DVD writer) Product: SCSI Drivers Version: 2.5 Kernel Version: Linux version 2.6.36-rc7-blueyed-00145-g50c6dc9 (root@base) (gcc version 4.4.5 (Ubuntu/Linaro 4.4.4-14ubuntu5) ) #2 SMP PREEMPT Mon Oct 11 21:53:45 CEST 2010 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Other AssignedTo: scsi_drivers-other@xxxxxxxxxxxxxxxxxxxx ReportedBy: linux-bugs@xxxxxxxxxx Regression: No The system log gets spammed via dmesg with several of the following errors per second: Oct 11 22:53:39 base kernel: [ 2147.766956] scsi host5: __pm_runtime_resume()! Oct 11 22:53:39 base kernel: [ 2147.766962] scsi host5: __pm_runtime_resume() returns 1! Apparently this refers to my DVD drive, according to the /proc files: >From /proc/scsi/scsi: Host: scsi5 Channel: 00 Id: 01 Lun: 00 Vendor: HL-DT-ST Model: DVDRAM GSA-4163B Rev: A100 Type: CD-ROM ANSI SCSI revision: 05 % cat /proc/scsi/sg/devices [...] 5 0 1 0 5 1 1 0 1 % cat /proc/scsi/sg/device_strs [...] HL-DT-ST DVDRAM GSA-4163B A100 This might be caused by CONFIG_PM_DEBUG=y, and might actually be expected. In this case, please excuse this report then - but consider making it less verbose. My /proc/config.gz unzipped: http://pastebin.com/knXt8nmw lspci -vvv: http://pastebin.com/iMWbaUPC Might this be related to the writer failing to detect rewritable media? (which might be a regression I still would have to investigate deeper into) (This might be related to https://bugzilla.kernel.org/show_bug.cgi?id=19712 - where only a "__pm_runtime_resume()!" is posted repeatedly.) -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
