Was that a migration from TrueNAS core to Scale? Did you run into any
regression specific to TrueNAS Scale? I heard Scale is less mature than Core.

My SW setup used to be stable until I added that NVME disk as an upgrade. I
really wish I can avoid any SW migration since the SW setup has been there
working just fine for 8+ years with quite a few weird customization -- XEN
virtualization, LXC container in dom0 served by TrueNAS core as a XEN guest.

XEN virtualization and PCI passthrough could be a factor in this problem but so
far I haven't found any evidence yet... My current top suspect is still the
APST feature in FreeBSD driver...
