@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'.
