This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed- xenial'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Under adverse circumstances the bug can result in data corruption and loss. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d554b5e1ca64d23e4f839e6531490fee8479fbaf nvme: Quirks for PM1725 controllers PM1725 controllers have a couple of quirks that need to be handled in the driver: - I/O queue depth must be limited to 64 entries on controllers that do not report MQES. - The host interface registers go offline briefly while resetting the chip. Thus a delay is needed before checking whether the controller is ready. Note that the admin queue depth is also limited to 64 on older versions of this board. Since our NVME_AQ_DEPTH is now 32 that is no longer an issue. Signed-off-by: Martin K.
