Hi Keith,

Thanks for the quick response and the suggestions. Unfortunately 'pcie_aspm=off' didn't seem to make a difference and when adding 'nvme_core.default_ps_max_latency_us=0' I get this:

[    4.035844] nvme 0000:0e:00.0: VPD access failed.  This is likely a firmware bug on this device.  Contact the card vendor for a firmware update
