Happy to provide more info or test patches, etc. what if you change the SATA link_power_management_policy to min_power? (In reply to Zhang Rui from comment #3) > what if you change the SATA link_power_management_policy to min_power? you can do this by changing /sys/class/scsi_host/host*/link_power_management_policy to "min_power". Ah ha. That does it indeed. ;) So, I guess you can close this... sorry for the noise. *** This bug has been marked as a duplicate of bug 116671 *** |
