Hi Juan, i have tried with your suggest many time but the problem still happens. I also tried with nvme_core.default_ps_max_latency_us=0 but no hope. I'm not sure the APST be disabled. How to check APST status when system booted? https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/nvme/host/core.c#n2282
