@Nils,
With the current default value, your NVMe will transit to PS4. So let's add 
kernel parameter 'nvme-core.nvme_core.default_ps_max_latency_us=2000' to test 
if PS3 also shares the same issue.
If this issue persists, use 'nvme-core.nvme_core.default_ps_max_latency_us=0' 
to turn APST off.

@Ben, 
Is your laptop XPS 9550/Precision 5510, too?

Please try 'nvme-core.nvme_core.default_ps_max_latency_us=5500', if the
issue persists, please try  'nvme-
core.nvme_core.default_ps_max_latency_us=200'.
