Hi,
> Attached a testpatch based on 4.1-rc2
Thanks. Unfortunately, this patch did not help: I saw no change in
behavior compared to vanilla 4.1-rc2.
I should probably mention that there is a slight difference in the log
output of the 3.16 and 4.1 kernels: The "xhci_hcd 0000:04:00.0: irq 42
for MSI/MSI-X" messages only show up with the older kernels.

Indeed doing "echo 'on' | sudo tee /sys/bus/pci/devices/*/power/control"
fixes the problem: When I subsequently plug in the disk, it is
recognized correctly. I confirmed this with an older kernel (the 3.16
Debian kernel, to be more precise). That's good to know, now I don't
need to reboot to a different kernel anymore to do fast backups ;-)
Kind regards,
Ralf
