The upstream author sent a patch set [1] according to this bug report (thanks guys!). Looks like 4.11 will disable APST and make it opt-in, and 4.12 will introduce a new quirk to avoid deepest power state. I'll backport the patch set once it lands at linux-nvme tree. [1]:

@sforshee: You would suggest an other solution, e.g. setting the default value for nvme_core.default_ps_max_latency_us to 0, this way it is still possible to enable the power saving features for experienced users without having an impact to everyone else :) -- You received this bug notification

Nils, from above use 'nvme-core.nvme_core.default_ps_max_latency_us=0' to turn APST off. That as my first step to confirm this is indeed related to APST and the same bug. If that doesn't do it, I'm afraid you might have another issue. -- You received this bug notification because you are a

I have to admit that I'm not sure how or where to set 'nvme- core.nvme_core.default_ps_max_latency_us=2000'. I assumed that it's a kernel boot parameter that I can add in grub? But when I do nothing changes and "sysctl -a", which I assumed should list the changed parameter does not show anything
