Hi Kelvin,
Please Use the current test kernel. Per cycle, for both slots:
1. Unplug both drives; confirm endpoints gone (lspci -D | grep 10000:0[23]
shows nothing).
2. While slots are empty, issue the root-port reset:
echo 1 > /sys/bus/pci/devices/10000:00:03.0/reset # Slot 65
echo 1 > /sys/bus/pci/devices/10000:00:05.0/reset # Slot 66
3. Replug both drives; check nvme list — both must come back with namespaces.
4. Repeat 3 cycles (same protocol as the runs that failed).
