Dear NVMe hackers,
I promise that this is the last time I'll spam this list.

After a reboot, the timeouts vanished.
I can now happily confirm that accessing the flash drive works using
kernel 4.6.0-rc7 and manually binding using:
echo 106b 2003 > /sys/bus/pci/drivers/nvme/new_id
No controller resets or other IO errors occur even with (moderately)
drive-intense activities like compiling and installing packages.
I'll submit a patch which will make the manual binding superfluous
tomorrow.
LLAP,
Carina
