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@kernel-bugs.osdl.org
ReportedBy: linux-bugs@thequod.de
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
[...]

% 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.

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.)
