Summary: sata hotplug doesn't work on ports where
link_power_management_policy=min_power
Product: IO/Storage
Version: 2.5
Kernel Version: 3.0.3
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Serial ATA
AssignedTo: jgarzik at pobox.com
ReportedBy: tcl_de at gmx.net
Regression: Yes
I recently upgraded to kernel 3.0.3 (from 2.6.38) and noticed that after the
upgrade sata hotplug doesn't work any more after I have set the port's
link_power_management_policy to min_power. After setting
link_power_management_policy back to max_performance hotplug still keeps not
working.
But sata hotplug works if I never set the policy to min_power.
I looked through recent libata commits and found out that I can make sata
hotplug work regardless of the link power management policy state again by
reverting
