I confirmed that the bug is still present in 4.1-rc2, and that reverting above commit on top of 4.1-rc2 fixes the issue. Furthermore, doing echo 'on' | tee /sys/bus/pci/devices/*/power/control before plugging in the disk is a work-around. I should note that I have udev set up to set power/control to "auto" for all PCI devices. Please try to reproduce this bug with latest kernel image. Sorry, I don't own the laptop any more, so I cannot test this. |
